Abstract:

Conventional CMOS-based logic circuits are approaching their limits when it comes to speed and energy consumption, so the development of new electronic components becomes critical. Memristor is a nano-structured special electronic device with the advantages of simple structure, low power consumption and easy integration. This invention supplys a new method for developing complex logic circuits. This article mainly presents the design of a five-person voter circuit. The OR/AND logic can be accomplished by varying the polarity of two parallel memristors. On the basis of the two logic circuits, adder and comparator are constructed. Further, based on the adder and comparator, a five-person voter is implemented. The correctness and rationality of the five-person voter based on MRL are confirmed via logistical analysis and simulation. Compared with the traditional logic circuits, the logic circuit designed in this paper has advantages in area cost. The realization of the five-person voter circuit further proves that the logic circuit based on memristor can be cascaded. The research results are expected to build more complex circuits, which may provide a reference for the design of other practical circuits.

Abstract:

Purpose The purpose of this study is to show that the humidity levels for surface insulation resistance (SIR)-related failures are dependent on the type of activators used in no-clean flux systems and to demonstrate the possibility of simulating the effects of humidity and contamination on printed circuit board components and sensitive parts if typical SIR data connected to a particular climatic condition are available. This is shown on representative components and typical circuits. Design/methodology/approach A range of SIR values obtained on SIR patterns with 1,476 squares was used as input data for the circuit analysis. The SIR data were compared to the surface resistance values observable on a real device printed circuit board assembly. SIR issues at the component and circuit levels were analysed on the basis of parasitic circuit effects owing to the formation of a water layer as an electrical conduction medium. Findings This paper provides a summary of the effects of contamination with various weak organic acids representing the active components in no-clean solder flux residue, and demonstrates the effect of humidity and contamination on the possible malfunctions and errors in electronic circuits. The effect of contamination and humidity is expressed as drift from the nominal resistance values of the resistors, self-discharge of the capacitors and the errors in the circuits due to parasitic leakage currents (reduction of SIR). Practical/implications The methodology of the analysis of the circuits using a range of empirical leakage resistance values combined with the knowledge of the humidity and contamination profile of the electronics can be used for the robust design of a device, which is also important for electronic products relying on low current consumption for long battery lifetime. Originality/value Examples provide a basic link between the combined effect of humidity and contamination and the performance of electronic circuits. The methodology shown provides the possibility of addressing the climatic reliability of an electronic device at the early stage of device design by using typical SIR data representing the possible climate exposure.

Abstract:

This paper mainly discusses the energy-saving design method for large weak electronic circuit. In large scale electronic circuit, there is no direct relevance between every two element modules. The traditional weak element circuit design concentrates in a single module, while ignoring module dependencies in energy-saving design, resulting in high energy consumption in large-scale electronic circuits. This paper proposes to establish the relevance energy-loss model for each model in the large-scale weak electronic circuit to obtain the energy consumption situation, and consider the energy consumption in module coordination to saving energy. The simulation results show that the proposed model used for large-scale energy weak circuit design can effectively reduce the energy consumption in weak circuit application.

Abstract:

In biological systems, individual phenotypes are typically adopted by multiple genotypes. Examples include protein structure phenotypes, where each structure can be adopted by a myriad individual amino acid sequence genotypes. These genotypes form vast connected ‘neutral networks’ in genotype space. The size of such neutral networks endows biological systems not only with robustness to genetic change, but also with the ability to evolve a vast number of novel phenotypes that occur near any one neutral network. Whether technological systems can be designed to have similar properties is poorly understood. Here we ask this question for a class of programmable electronic circuits that compute digital logic functions. The functional flexibility of such circuits is important in many applications, including applications of evolutionary principles to circuit design. The functions they compute are at the heart of all digital computation. We explore a vast space of 10 45 logic circuits (‘genotypes’) and 10 19 logic functions (‘phenotypes’). We demonstrate that circuits that compute the same logic function are connected in large neutral networks that span circuit space. Their robustness or fault-tolerance varies very widely. The vicinity of each neutral network contains circuits with a broad range of novel functions. Two circuits computing different functions can usually be converted into one another via few changes in their architecture. These observations show that properties important for the evolvability of biological systems exist in a commercially important class of electronic circuitry. They also point to generic ways to generate fault-tolerant, adaptable and evolvable electronic circuitry.

Abstract:

Simulation programs are widely used in the design of analog electronic circuits to analyze their behavior and to predict the response of a circuit to variations in the circuit components. A fuzzy inference system (FIS) in combination with these simulation tools can be applied to identify both the main and interaction effects of circuit parameters on the response variables, which can help to optimize them. This paper describes an application of fuzzy inference systems to modeling the behavior of analog electronic circuits for further optimization. First, a Monte Carlo analysis, generated from the tolerances of the circuit components, is performed. Once the Monte Carlo results are obtained for each of the response variables, the fuzzy inference systems are generated and then optimized using a particle swarm optimization (PSO) algorithm. These fuzzy inference systems are used to determine the influence of the circuit components on the response variables and to select them to optimize the amplifier design. The methodology proposed in this study can be used as the basis for optimizing the design of similar analog electronic circuits.

Abstract:

Analog circuits are of great importance in electronic system design. Recent evolutionary design results are usually small-scale analog circuits. This paper proposes a real-coded mechanism and uses it in the large-scale analog circuit evolutionary design. The proposed scheme evolves the circuit topology and size to a uniformed continuous space, in which the circuit representation is closed and of causality. Experimental results show that the proposed scheme can work successfully on many analog circuits with different kinds of characteristics. Comparing with other evolutionary methods before, the proposed scheme performs better on large-scale problems of circuit synthesis with higher search efficiency, lower computational complexity, and less computing time.

Many circuits appearing in pulse and digital electronics are multi-diode networks. In such networks diodes can typically be modeled as either on or off. Determining the states of all diodes can become quite challenging (and sometimes frustrating) for the undergraduate student who has not yet developed intuitive insight into the subject. In this paper a logical and systematic procedure for determining the state of all the diodes in a multi-diode network is presented to simplify the circuit analysis, ease the frustration, and help the student develop physical insight into the design and analysis of electronic circuits.

Full text

Abstract:

A flex circuit connects the stationary electronic components in a hard disk drive to the rotating arm that carries the read/write heads and positions them above data tracks on the disk. Flex circuits are conventionally formed as a laminate of polyimide substrate, adhesive, and copper conductors. Deformation of a flex circuit is discussed in the context of the following stages: the initial unstressed shape, configurations in which stresses set and relax in response to elevated temperature, equilibrium, and small amplitude vibration. The model involves displacements of the flex circuit in the directions tangent and normal to the local equilibrium shape, and those motions couple with the arm’s dynamics. Nonlinearity associated with finite curvature, partial elastic springback, and the arm’s geometry and inertia properties are incorporated within the vibration model to predict system-level natural frequencies, mode shapes, and coupling factors between the circuit and the arm. Laboratory measurements using noncontact laser interferometry validate the model with respect to the circuit’s shape, stiffness, restoring moment, and natural frequencies. The primary degrees of freedom for optimizing flex circuit design are the thicknesses of the individual layers within the circuit, free length, and the locations and slopes of the circuit’s attachment points to the arm and electronics block. The model’s predictions and trends developed from a case study in free length are discussed with a view toward reducing coupling between the circuit and arm in certain vibration modes.

Abstract:

This article examines the existing software applications for electronic circuit prototyping that can help evaluate the operation of the entire circuit based on specified parameters and find the best options. Using the TAC application and the Arduino library components, projects and instructions for creating and testing electronic circuits were developed. The resulting application was tested for capabilities and efficiency. The interface design and settings were also assessed to determine whether they simulate real conditions. The functionality of TAC application made it possible to generate alternate circuits. The results of software testing showed that using the application speeds up the learning process significantly when compared to traditional methods and helps eliminate problems that may emerge when designing and assembling circuits. The application may be useful in designing complex electronic circuits and developing teaching aids for students in technical fields.

Abstract:

Field-effect transistors (FETs) in conventional electronic circuits are in contact with the high-thermal-conductivity substrate. In contrast, FETs in novel silicon-on-insulator (SOI) circuits are separated from the substrate by a thermally resistive silicon-dioxide layer. The layer improves the electrical performance of SOI circuits. But it impedes conduction cooling of transistors and interconnects, degrading circuit reliability. This work develops a technique for measuring the channel temperature of SOI FETs. Data agree well with the predictions of an analytical thermal model. The channel and interconnect temperatures depend strongly on the device and silicon-dioxide layer thicknesses and the channel–interconnect separation. This research facilitates the thermal design of SOI FETs to improve circuit figures of merit, e.g., the median time to failure (MTF) of FET–interconnect contacts.

Abstract:

Digital multiplier circuits are used in computers. A multiplier is an electronic circuit used in digital electronics to multiply two binary numbers. Multiplier circuits are used in ALU for binary multiplication of signed and unsigned numbers. The delay, area and power consumption are the 3 most important design specifications a chip designer has to consider. Delay of the circuit is directly proportional to the delay of a multiplier. Increased delay in the multiplier leads to higher delay in the circuit. Therefore research is carried out as to how to reduce the delay of the multiplier block so as to reduce the delay of whole circuit. The main purpose is to deal with high speed and lower power consumption even after decreasing the silicon area. This makes them well-suited for numerous complex and convenient VLSI circuit implementations. The fact however, remains that area and speed are two contradictory performance restrictions. Hence, increase in speed always results in the use of more and complex hardware. Different arithmetic techniques can be used to implement different multiplier circuits. The focus of this paper is to implement various multiplier circuit and compare them. The timing signals can be observed using software such as Modelsim and Xilinx.

Abstract:

Estimating peak power involves optimization of the circuit's switching function. The switching of a given gate is not only dependent on the output capacitance of the node, but also heavily dependent on the gate delays in the circuit, since multiple switching events can result from uneven circuit delay paths in the circuit. Genetic spot expansion and optimization are proposed in this paper to estimate tight peak power bounds for large sequential circuits. The optimization spot shifts and expands dynamically based on the maximum power potential (MPP) of the nodes under optimization. Four genetic spot optimization heuristics are studied for sequential circuits. Experimental results showed an average of 70.7% tighter peak power bounds for large sequential benchmark circuits was achieved in short execution times.

Abstract:

Advancement of classical silicon-based circuit technology is approaching maturity and saturation. The worldwide research is now focusing wide range of potential technologies for the “More than Moore” era. One of these technologies is thermal-electronic logic circuits based on the semiconductor-to-metal phase transition of vanadium dioxide, a possible future logic circuits to replace the conventional circuits. In thermal-electronic circuits, information flows in a combination of thermal and electronic signals. Design of these circuits will be possible once appropriate device models become available. Characteristics of vanadium dioxide are under research by preparing structures in laboratory and their validation by simulation models. Modeling and simulation of these devices is challenging due to several nonlinearities, discussed in this article. Introduction of custom finite volumes method simulator has however improved handling of special properties of vanadium dioxide. This paper presents modeling and electro-thermal simulation of vertically structured devices of different dimensions, 10 nm to 300 nm layer thicknesses and 200 nm to 30 μm radii. Results of this research will facilitate determination of sample sizes in the next phase of device modeling.

Abstract:

One important step of the optimization of analog circuits is to properly size circuit components. Since the quantities that define specification may compete for different circuit parameter values, the optimization of analog circuits befits a hard and costly optimization problem. In this work, we propose two contributions to design automation methodologies based on machine learning. Firstly, we propose a probability annealing policy to boost early data collection and restrict electronic simulations later on in the optimization. Secondly, we employ multiple gradient boosted trees to predict design superiority, which reduces overfitting to learned designs. When compared to the state-of-the art, our approach reduces the number of electronic simulations, the number of queries made to the machine learning module required to finish the optimization.

Abstract:

There has been enormous worldwide effort to increase the volumetric efficiency of electronic packaging. Much of this effort has been driven by the telecommunications industry that has succeeded in reducing cell phone size while simultaneously increasing functionality. The hearing aid business has always had the need to use extremely small electronic packaging because hearing aids pack electronics into the ear canal. In recent years hearing aid microelectronic packaging has moved from ceramic hybrid based packaging to a flexible circuit based technology. Due to the size and shape of all types of hearing aids, flexible circuits need to be folding and bent to fit inside hearing aid cases. In order to reduce space, bends and folds are pushing conventional wisdom on the limits of mechanical integrity. There is little published information regarding bendability of multilayer flexible circuits for class I medical device applications. This paper will examine bending and folding effects on a Polyimide/Adhesive/Copper/Polyimide/Copper/Adhesive/Polyimide structural stack-up on a test coupon and a HDI flexible circuit. A forming tool that controls every aspect of bend testing will be discussed. A variety of factors were investigated including bend angle, thickness of the circuit, bend radius, foil weight, copper materials, construction, and frequency of flexing. The circuit electrical resistance, microstructure and crack initiation were monitored during the process and will be examined. Failure mechanisms will be discussed as well as their impact on design.

Abstract:

In this paper, a novel grid multiscroll chaotic electronic oscillator with simple circuit design is proposed. The proposed grid multiscroll chaotic circuit only needs two current feedback operational amplifiers (CFOAs) as current integrators, passive RC, and nonlinear elements in the form of current stair nonlinear function series (SNFS) realized with CFOAs. Compared with existing grid multiscroll circuits such as Chua's circuit and Jerk circuit, etc., its component count is reduced. Mathematical models of the proposed generators are derived. Theoretical analysis and numerical simulations of the derived models are included. Moreover, the experimental results are verified that the proposed simpler chaotic electronic oscillator can generate grid multiscroll chaotic attractors with higher frequency.

Abstract:

Purpose The paper focuses on design, fabrication and characterization of electromagnetic microgenerators with integrated rectifying circuits to convert AC output signal to DC one. The work includes research on simulation of voltage-rectifying circuits, including charge pump, realization of the experimental printed circuit board (PCB) with selected electronic circuits and the execution of the final structure with integrated rectifying circuit. Measurements were performed on these circuits. Design/methodology/approach Electromagnetic microgenerators include multipole permanent magnets secured on rotor three-phase brushless direct current (BLDC) motor and planar multilayer multiple coils. These were fabricated using low temperature co-fired ceramics (LTCC) technology. In our experiment, six rectifying circuits were simulated and tested with a structure consisting of eight layers of coils and with an outer diameter of 50 mm fabricated earlier. Findings The microgenerator with Graetz bridge generates higher output power than the modified charge pump at the same rotary speed. However, it is less stable for the distance change between the structure and the magnets than the modified charge pump, which has more constant output power in a wider range of load resistance. Originality/value The presented electronic rectifying circuits are novel for LTCC-based electromagnetic microgenerator application. The structure with integrated rectifying circuits allows generation of electrical output power larger than 100 mW at the rotor speed of about 8,000 rpm.

Abstract:

Multi-threshold voltage CMOS (MTCMOS) is the most widely used circuit technique for suppressing the subthreshold leakage currents in idle circuits. When a conventional sequential MTCMOS circuit transitions from the sleep mode to the active mode, significant bouncing noise is produced on the power and ground distribution networks. The reliability of the surrounding active circuitry is seriously degraded. A dynamic forward body bias technique is proposed in this paper to alleviate the ground bouncing noise in sequential MTCMOS circuits without sacrificing the data retention capability. With the new dynamic forward body bias technique, the peak ground bouncing noise is reduced by up to 91.70% as compared to the previously published sequential MTCMOS circuits in a UMC 80 nm CMOS technology. The design tradeoffs among important design metrics such as ground bouncing noise, leakage power consumption, active power consumption, data stability, and area are evaluated.

Abstract:

This paper describes our InP-based heterojunction bipolar transistor (HBT) technologies and circuit design techniques for small-scale-integration (SSI) and medium-scale-integration (MSI) circuits for 40- to 100-Gbit/s-class optical communications systems. The circuits include a sub-4-ps emitter-coupled logic (ECL) gate, 100-Gbit/s selector circuit, 90-Gbit/s decision circuit, 50-Gbit/s 4:1 multiplexer (MUX) and 1:4 demultiplexer (DEMUX) ICs, aver-40-Gbit/s 16:1 MUX IC, and 40-Gbit/s full-clock-rate DEMUX with a clock and data recovery (CDR) circuit. This paper demonstrates that InP-based HBT technologies and our circuit design techniques are attractive for fabricating ultrahigh-speed SSI circuits with data rates approaching 100 Gbit/s and low-power MSI circuits with data rates of over 40 Gbit/s.

Abstract:

This paper presents a scheme for the modified chaotic circuits based on inductance integration. In view of the fact that the DC resistance of an inductor in the circuit cannot be ignored, this way of constructing the circuits is provided that can eliminate its influence on the integral circuits. By means of cascading an inverting adder circuit and inductance integral circuit, the output signal of the integral circuit is fed back to the inverting adder circuit, and its additive term is artificially added to match the actual inductance integrated circuit to achieve integral circuit based on the actual inductor which can offset the effect of its DC resistance. In order to verify the generality of the design, the process of designing Lorenz chaotic circuit is given and its attractors can also be observed from the oscilloscope.

Abstract:

This article deals with a new approach to an intelligent analog circuit design. The iterative closed loop design methodology adopts an expert system approach to provide topological synthesis, the SPICE circuit simulator to evaluate the circuit performance and a new approach of the diagnostic expert system to provide advice on how to improve the design. Unlike previous design methods, this approach introduces formal circuit representation for both numerical and heuristic knowledge of the design system. The predicate logic circuit representation is proposed to introduce a new concept of a formal analog circuit description language. The language syntax and semantics provide precise symbolic description of analog circuits functionality at different levels of hierarchy and connectivities together with transistor sizes of CMOS circuits at the transistor level. Different levels of hierarchy with circuit structures and performance parameters are presented in detail. It is shown how sentence conversion rules of language grammar can be used to derive transistor level circuits from input performance specifications through all intermediate levels of hierarchy. The implementation of the methodology and associated experimental results for CMOS operational amplifier designs are presented.

Abstract:

The interconnection of electronics and textile circuits is still a main challenge for the fabrication of reliable smart textiles. This paper investigates the thermoplastic adhesive bonding technology. Electronic modules are bonded to textile substrates with a thermoplastic non-conductive adhesive (NCA) film. The modules are placed onto textile circuits with an NCA-film in-between. By applying pressure and heat, the adhesive melts and contact partners touch. Subsequently cooling solidifies the NCA resulting in an electrical and mechanical contact of the electronic module and the textile circuit. This paper shows the suitability of this technology for knitted, woven, non-woven and embroidered fabrics with metal coated yarns as well as with litz-wires as conductors. Besides, it shows that the interconnection process works well with thermoplastically insulated conductors. In addition, the design of interposers has been improved in respect to contact formation and miniaturization compared to previous publications. The pitch of the contact pads is set to 1.27 mm. A textile display was realized with smart RGB-Pixels, which are controlled by an I²C-bus on a quadrupolic woven substrate. It demonstrates the applicability and the potential of this technology.

Abstract:

Abstract. A classroom activity involving the construction, calibration, and testing of electronic circuits was introduced to an advanced hydrology class at the postsecondary level. Two circuits were constructed by students: (1) a water detection circuit and (2) a hybrid relative humidity (RH)/air temperature sensor and pyranometer. The circuits motivated concepts of systems science, modelling in hydrology, and model calibration. Students used the circuits to collect data useful for providing inputs to mathematical models of hydrological processes. Each student was given the opportunity to create a custom hydrological model within the context of the class. This is an example of constructivist teaching where students engage in the creation of meaningful knowledge, and the instructor serves as a facilitator to assist students in the achievement of a goal. Analysis of student-provided feedback showed that the circuit activity motivated, engaged, and facilitated learning. Students also found the activity to be a novel and enjoyable experience. The theory of circuit operation and calibration is provided along with a complete bill of materials (BOM) and design files for replication of this activity in other postsecondary classrooms. Student suggestions for improvement of the circuit activity are presented along with additional applications.

Abstract:

This paper presents a circuit architecture for a new integrated on chip test method for microwave circuits. The proposed built-in-self-test (BIST) cell targets a direct low-cost measurement technique of the gain and the 1 dB input compression point (CP1) of a K-band satellite receiver in the 18–22 GHz frequency bandwidth. A signal generator at the radiofrequency (RF) front end input of the device under test (DUT) has been integrated on the same chip. To inject this RF signal, a loopback technique has been used and the design has been accommodated for it. This paper focuses on the design of the most sensitive block of the BIST circuit, i.e. the RF signal generator. This circuit, fabricated in a SIGe:C BiCMOS process, consumes 10 mA. It presents a dynamic power range of 17 dB (−41; −24 dBm) and operates in a frequency range of 5.6 GHz (17.5; 23 GHz). This BIST circuit gives new perspectives in terms of test strategy, cost reduction, and measurement accuracy for microwave-integrated circuits and could be adapted for mm-wave circuits.

Abstract:

Electromagnetic compatibility has to be given enough attention in the design of hybrid Integrated Power Electronic Module (IPEM) due to the sharply decreased distances between power devices and the control/driving circuits as compared to such distances for conventional power electronic equipment built with discrete devices. The high dν/dt, di/dt and high frequency parasitic ringing emanating from the switching circuit can cause serious EMI within the control/driving circuit due to cross-coupling. This paper analyzes the capacitive and inductive cross-coupling problems inside an IPEM. Finite Element Method (FEM) is used to extract the mutual capacitances between the metal bars in the model. Then the influence of dν/dt can be estimated. The high frequency circulating current in the bridge circuits is also investigated since it causes magnetic interference due to mutual inductance coupling. The mutual inductance is calculated with the simplified Partial Element Equivalent Circuit (PEEC) approach and image method. The experiment validates the effectiveness of this evaluation. In the end, the electromagnetic shielding is discussed.

The most general parameter of the electronic circuit is its sensitivity. Sensitivity analysis helps circuit designers to determine boundaries to predict the variations that a particular design variable will generate in a target specifications, if it differs from what is previously assumed. There are two basic methods for calculating the sensitivity: matrix methods and graph methods. The method described in this article is based on a graph, that contains separate input ad output nodes for each phase. This makes it possible to determine the transmission sensitivity even between partial switching phases. The described fully-graph method is suitable for switched current circuits and switched capacitors circuits, too

The alternative technology of DNA strands is the rapid development of existed biotechnological methods for calculating new types of faster growth. In addition, a new idea for the odd judgment logic circuit based on DNA strand displacement reaction technology is proposed to solve practical problems in mathematics, and which is widely used for those various logic circuits and computing systems to acquire important roles in biological computers.

It is a good technical support and a good theoretical basis provided for the future development of biological computers through the odd judgment logic circuit.

Abstract:

The project Meeting the Design Challenges of nano-CMOS Electronics ( http://www.nanocmos.ac.uk ) was funded by the Engineering and Physical Sciences Research Council to tackle the challenges facing the electronics industry caused by the decreasing scale of transistor devices, and the inherent variability that this exposes in devices and in the circuits and systems in which they are used. The project has developed a grid-based solution that supports the electronics design process, incorporating usage of large-scale high-performance computing (HPC) resources, data and metadata management and support for fine-grained security to protect commercially sensitive datasets. In this paper, we illustrate how the nano-CMOS (complementary metal oxide semiconductor) grid has been applied to optimize transistor dimensions within a standard cell library. The goal is to extract high-speed and low-power circuits which are more tolerant of the random fluctuations that will be prevalent in future technology nodes. Using statistically enhanced circuit simulation models based on three-dimensional atomistic device simulations, a genetic algorithm is presented that optimizes the device widths within a circuit using a multi-objective fitness function exploiting the nano-CMOS grid. The results show that the impact of threshold voltage variation can be reduced by optimizing transistor widths, and indicate that a similar method could be extended to the optimization of larger circuits.
