Full textContrary to digital design, analog design suffers from a real delay in the software solution that enables fast and reliable design. In this PhD, three approaches are proposed. The first is the methodological approach. At this level we recommend a "top-down" hierarchical approach. It consists of partitioning the system to size into sub-blocks of elementary functions whose specifications are directly inherited from the system level specification. Next, we aimed to reduce design time through the exploration of optimal solutions using hybrid algorithms. We attempted to take advantage of the rapid global search and local search accuracy. The interest of hybrid search algorithms is that they allow to conduct effective exploration of the design space of the circuit without the need for prior knowledge of an initial design. This can be very useful for a beginner designer. Finally, we worked on the acceleration of time simulations proposing the use of meta-models which present a more reduced time than electrical simulation models. Meta-models are obtained automatically from extracting results of electrical simulations

Full textIn the era of “Internet of Things”, conventional silicon-based circuits are not the only option to realize sensor interfaces. Electronic devices based on flexible materials are an interesting approach to interface with sensors connected to our everyday life, e.g.: clothes, packages, skin and into the human body. In this thesis, we propose a formalization of the:- Transistor fabrication process using organic and flexible materials.- Analog and digital circuit design using these transistors. The main contribution of this work can be summarized in the following:- Optimization of the fabrication and characterization process of two technologies: the first by shadow masks with an easy-to-fabricate procedure, the second by self-alignment and photolithography.- Modeling and parameter extraction for process variation aware analog design.- Customization of an open source VLSI CAD tools (Alliance©) for circuit design and layout of OTFT.- Design, fabrication and measurement of OTFT analog front-ends (OTAs, Comparators, Analog-to-Digital Converters,…) and basic digital circuits (Inverters, Logic Gates, …).This work achieved very interesting results and it opens a wide scope of future applications in the field of Flexible organic electronics

Full textThe purpose of this thesis work is to investigate circuit design techniques to improve the robustness to Total Ionizing Dose (TID) of analog circuits within electronic systems embedded in space probes, satellites and vehicles. Such circuits often contain bipolartransistor components which are quite sensitive to cumulated radiation dose. However highly integrated CMOS technology has been shown to exhibit better natural TDI hardening.The approach proposed here is a hardening by design using a full CMOS semiconductor technology commercially available from ST Microelectronics calledHCMOS9A. The proposed generic hardening design methods will be seen to be compatibleand applicable to other existing or future process technologies. Furthermore this approach addresses the issue of ever-increasing development cost and access to hardened technologies.The first TID hardening technique proposed is applied to a full-CMOS voltage reference. This technique does not involve p-n junctions nor any particular layout precaution but instead is based on the subtraction of two different threshold voltages which allows the cancellation of TDI effects. While the use of advanced commercial CMOS technologies for specific radiation hardened applications is becoming more common, these technologies suffer from larger inputoffs et voltage drift than their bipolar transistor counterparts, which can impact system performance. The second technique studied is that of auto-zeroing, which is an efficient method to reduce the complex offset voltage drift mechanisms of operational amplifiers due to temperature. The purpose here is to prove that this technique can also cancel input offset voltage drift due to TID.Index term : hardening, cumulated dose, CMOS technology, voltage reference,operational amplifier

Full textThe analogue CMOS integrated circuits dedicated to signal behaviour are not so suitable with new technologies improvement and would have accurate performances, low power and high speed. Integrated circuits have one more difficulty of integration density. All works present in this these take place with the study of architecture based on current mode approach more suitable with new technologies improvement. So, a first approach remember the bipolar structures introduced by the translinear circuits. A second approach propose an equivalence between translinear and CMOS circuits. The current mode approach allows to propose a contact less emitter receiver. The emitter system works with a modulated 13. 56 MHz radio frequency signals. The receiver was realised and tested with CMOS 0. 5 micrometer in a relationship with INSIDE TECHNOLOGIES industry and the L2MP laboratory

Full textCircuit simulation is a necessary step during the design of integrated circuits. Matrical resolution methods used in classical simulators are not well suited for the simulation of circuits with a great number of components, due to untractable memory occupation and computing time. The simulator MAXIM has been developped in order to allow such simulations. In MAXIM, the circuit is described using macromodels, and the resolution method is based on an ordered graph. This thesis presents the last evolutions of MAXIM concerning the simulation of analog circuits and functionnal simulation. The operation and the use of the macromodels developped for these purposes are described. The data structures and the procedures used to implement a new component model are detailed so that users can develop their own libraries. Finally, the possibilities of MAXIM for multilivel simulation are shown in a few examples. These possibilities can be used in circuits comprising both logical and analog properties by using electrical and functionnal macromodels

Full textThe design of specific CAO tools for analog integrated circuits' automatic layout has become necessary, especially in the field of telecommunications, so that Analog / Digital circuits may be implemented very quickly. These specific tools have to minimize the total area used and to insure that the circuit will work properly at the end. This thesis describes two new softwares which belong to a complete system for analog integrated circuits'automatic layout. The first one generates MOS transistors whose global shape may be defined by the designer so that the component fits well in the entire layout. The second one is an analog router which draws the necessary interconnections between all the cells in the circuit and takes into account all the present parasitic elements (resistors and capacitances). New layout methodologies have been introduced in these two tools which have been fully integrated in a CAD environment so that the user has as much control as possible over the obtained results

Full textWith the development of the Internet of things, the number of connected devices is in constant increase. These objects use a large amount of data including personal credentials. Therefore, security has become a major constraint for System on Chips (SoCs) designers. Moreover, in a context more and more aggressive in terms of performances and time to market, it is important to find low cost security solutions. Although the hardware security is often treated from a digital point of view, almost every SoCs is also using analog and mixed IP. Thus, this work presents different steps to improve the security of analog IPs, from vulnerability analysis to countermeasures design validation, and behavioral modeling in the context of mixed signals and low cost applications. To protect any system, the first requirement is to know its vulnerabilities. To do so, a vulnerability analysis methodology dedicated to analog circuit has been developed. Using the results of this analysis, countermeasures can be designed during the development of the circuit and not at the end. The circuit security is thus improved without dramatically increasing its cost in terms of design time. The analysis of a clock system generator, an analog IP widely used in current SoCs and composed with various sub-circuits, has shown fault attacks using Laser Photoelectric Stimulation (LPS) or supply voltage glitches as important threats. After having identified the 2 previous attacks types as major threats, their effects on analog circuits are analyzed. Existing countermeasures are then compared and evaluated for the protection of analog IPs. To complete these solutions, two analog detectors have been designed to detect laser and supply voltage glitch attacks considering SoCs level constraints. Electrical test of these detectors processed on CMOS 28nm FD-SOI technology proved their efficiency. Theoretical vulnerability analysis has shown some difficulties. Indeed, analog circuits are sensitive to numerous parametrical faults. Also, the high interconnection of various sub-circuits makes the faults propagation analysis quite difficult. To help this analysis, electrical simulations at transistor level are necessary. These simulations are quite long and, so the behavioral modeling of analog circuits to help the analysis of supply voltage glitch attack effects has been studied. To do so, the developed models must be developed according different constraints presented in this report and applied to the behavioral modeling of a real analog circuit. This illustration proved that behavioral models can be used to help to identify which attack shapes are the most likely to induce faults in the circuit

Full textThesis work are presented in the context of the integrated circuits design in advanced CMOS technology for ultra low power RF applications. The circuits are designed around two concepts. The first is the use of the inversion coefficient to normalize the transistor as a function of its size and its technology, this allows a quick analysis for different performances or different technologies. The second approach is to use a figure of merit to find the most appropriate polarization of a circuit based on its performance. These two principles were used to define effective design methods for two RF blocks: low noise amplifier and oscillator

Full textThe main topic of this work is the design of original radiofrequency active filter topologies in Silicon BiCMOS technology. In a first part, the state of the art of the different existing integrated technologies is described. In a second part, we present the design of the two active filters based on recursive principles. The first circuit, non-tunable, uses a differential amplifier in order to achieve signal summation. The second circuit, based on a cellular approach of recursive filters, can be tuned independently in terms of gain, bandwidth and central frequency. In a third part, we propose two original solutions for the realisation of integrated reconfigurable channelized filters. With such topologies, and using low-order filters, excellent performances can be achieved in terms of selectivity thanks to the generation of transmission zeros

Full textAs the technological processes of integration on silicon evolve by increasing the fine engraving and the integration density, digital processing has become faster at a lower cost in area and power consumption. This reduction in size is made at the expense of analog blocks' precision. The idea is to take advantage of the performance offered by digital circuits to release the specifications for analog blocks and globally win area occupation and consumption. Yet, analog-digital mixed circuit designers are faced with a situation where they have to choose between a purely analog design flow or a pure digital design flow, each ignoring the other. In this thesis, we introduced a new mixed-signal design flow, which aims at unifying both digital and analog design flows. Our design flow is divided into three steps: a placement step, a global routing step and a detailed routing step. During the placement step, the designer describes the relative placement and a set of constraints and our placement tool will generate all the valid placements respecting these constraints. The global routing step determines approximately the shortest path to connect the connectors according to a netlist. The shortest paths take into account several constraints such as symmetry constraints or avoiding obstacles. Finally, the detailed routing step completes the construction of each wire and resolve overlap issues of the wires. Our design flow has been applied to several analog and mixed-signal circuits, placed and routed within a few seconds. Our main goal is to give control to the designer all along the layout design flow steps

Full textThe development of an analogue application is long and often requires multiple iterations. However, electronics requires products with short time-to-market: short design and production cycle. In front of this challenge, the analogue designer is deprived of methodologies and tools contrary to the digital designer who benefits a broad range of programmable logic devices. This thesis exposes the contribution to the design of a programmable analogue circuit which integrates configurable cells for analogue computation targeting applications of sensor conditioning, carrying out operations of linearization. In most cases, the response curve of the sensor is not linear or the sensor conditioner introduces a non-linearity. This application is related to an industrial need with conditions of reduce cycle and development cost. After a state of the art in the field of analogue programmable devices both at the university level and the industrial level, the specifications of the required cell are exposed. The analogue computation cell must fulfill the functions of amplification, addition, substraction, multiplication, division and square root. This cell is completely differential at input and output. Thereafter, the cell of computation based on multipliers and inverting amplifiers, is described and characterised in simulation and experiment. The experimental characterisation highlights offsets, all related to problems of componant matching. This is why, a second cell was developed allowing to compensate for these offsets. Results show that the performances of the multiplier are improved in term of linearity and offset. Lastly, a network of eight computation cells was designed for the validation of the cell performances through the example of a resistive sensor linearization

Full textThe growing complexity of modern chips poses challenging test problems due to the requirement for specialized test equipment and the involved lengthy test times. This is particularly true for heterogeneous chips that comprise digital, analogue, and RF blocks onto the same substrate. Many research efforts are currently under way in the mixed-signal test domain. Theses efforts concern optimization of tests at the production stage (e. G. Off-line) or during the lifetime of the chip (on-line test). A promising research direction is the integration of additional circuitry on-chip, aiming to facilitate the test application (Design For Test) and/or to perform Built-In-Self-Test. The efficiency of such test techniques, both in terms of test accuracy and test cost, must be assessed during the design stage. However, there is an alarming lack of CAT tools, which are necessary, in order to facilitate the study of these techniques and, thereby, expedite their transfer into a production setting. In this thesis, we develop a CAT platform that can be used for the validation of analogue test techniques. The platform includes tools for fault modeling, injection and simulation, as well as tools for analogue test vector generation and optimization. A new statistical method is proposed and integrated into the platform, in order to assess the quality of test techniques during the design stage. This method aims to set the limits of the considered test criteria. Then, the different test metrics (as Fault coverage, Defect level or Yield loss) are evaluated under the presence of parametric and catastrophic faults. Some specific tests can be added to improve the structural fault coverage. The CAT platform is integrated in the Cadence design framework environment

Full textThe aim of this thesis is to study the contributions and the limitations of Independently Driven Double Gate MOS transistors in regard of the low frequency analog design. This device is one of the candidates for the replacement of the current bulk MOS technology since the gate length of the transistors cannot be efficiently decreased under 30nm. Even if the IDGMOS technology is mainly designed for digital and radio frequency applications, the independent drive of the gates should also improve the design of analog circuits ant it would provide solutions to the future circuits issues. First, this work focuses upon the IDGMOS’s behaviour, going a little deeper into the effects of the coupling that exists between its interfaces. Using the electrical characteristics of the transistor and simplifying its model, this report then reviews the static and dynamic laws of the component in order to extract a simple description of its operation modes. Secondly, a state of the art concerning both the future environment and issues is presented, followed by the solutions which currently exist using the standard MOS technology. A brief comparison between an advanced MOS technology and an IDGMOS model fitted on the ITRS parameters is given. However, these ideal parameters prevent this work from establishing a practical conclusion whereas the aforementioned theoretical studies can be used for providing a better understanding of the IDGMOS contributions. Those are reviewed just before the last part of the report which presents some basic analog circuits and their enhancement using double gate transistors. This chapter first emphasizes each important aspect of the device operating within the circuits and it thus concludes on an interesting comparison between two complete low supply voltage amplifiers, the first one designed using IDGMOS transistors and the other one based on bulk driven MOS devices

Full textElectronics and semiconductor are evolving at an ever-increasing rate. New technologies are also introduced to extend CMOS into nano/molecular scale MOSFET structures. Tighter time-to-market needs are pressing the need for an automated reliable analog design flow. Automatic layout generation is a key ingredient of such flow whose design challenges are drastically exacerbated when more complex circuits and newer technologies must be hosted. The thesis presents a designer-assisted, reusable and optimized analog layout generation flow that addresses the challenges facing the automation of analog circuits. It is part of CHAMS project developed in LIP6. It has been developed in 3 phases. Firstly, we designed a library of analog Smart Devices that are parameterized, reusable, and with different layout styles. A generic language was used to describe these Devices to ease the technology migration and the layout-induced parameters calculation. Secondly, we developed the tools to generate the layout of complex circuits using the library of Smart Devices, the technology files and the designer's geometrical placement constraints needed to guarantee a certain performance. An intelligent topological representation was used to efficiently place the circuit modules given the designer's set of constraints. Thirdly, we created algorithms to optimize the layouts for different aspect ratios to minimize the area and the routing parasitic. In parallel the algorithm directly calculates and back-annotates the layout-dependent parasitic parameters. This work provides a reliable and efficient solution to allow a fast, optimized and parasitic effects-aware layout generation of complex analog circuits

Full textOne of the main key points to enable mixed-signal BIST solutions is the development of efficient on-chip analog signal generators that can provide appropriate test stimuli and replace costly external signal generators in standard analog and mixed-signal functional test protocols. In this line, we present in this thesis different sinewave generation strategies based on harmonic cancellation techniques to design a high-frequency on-chip sinusoidal synthetize. The proposed generators employ digital hardware to provide a set of phase-shifted digital square-wave signals. These square-wave signals are scaled and combined using different harmonic cancellation strategies in a simplified current-steering DAC. The selected generator allows the cancellation of all harmonic components up to the eleventh. Additionally, a simple calibration strategy has been devised to compensate the impact of process variations and mismatch on the effectiveness of the harmonic cancellation. The simplicity of the circuitry makes this approach suitable for mixed-signal BIST applications. Electrical simulations of a 28nm FDSOI design and experimental results are provided to validate the functionality of the proposed signal generator. Obtained results show a calibrated performance around 52dB of SFDR for a generated sinusoidal signal at 166 MHz

Full textReliability of analog and mixed signal circuits fabricated using complementary metaloxide semiconductor technologies in the deep-submicrometer technology nodes is significantly affected by process, voltage and temperature (PVT) variations. Degradationinduced due to aging mechanisms like bias temperature instability, hot carrier injection leads to additional challenges in design of reliable circuits. PVT variations and aging mechanisms together lead to lifetime degradation of device and circuit performance.There are many studies in the literature of the reliability of MOS transistors. Few studies have been conducted on the impact of their reliability on circuits.This research will study the impact of the deterioration of the MOS transistors on the performance of the developed circuits for analog and mixed applications (low dropout voltage regulator LDO, phase locked loop PLL, voltage controlled oscillator VCO, digital to analog converter CAN, power amplifier PA).Degradation lifetime induces the degradation of the threshold voltage and the drain. The surveys are conducted using aging simulations supporting models of aging mechanisms developed by our team and measurements of circuits implemented in 28nmFDSOI technology. Accelerated tests were used to evaluate the aging effect. Appropriate correction techniques for overcoming aging-induced degradation of circuit performance are proposed and studied.The DC and AC performances of LDO were analyzed before and after aging. The stress induces a degradation of these performances because of the effect of the mechanism of injection of hot carriers (HCI) on the transistors and the Matching induced in the pair of transistors responsible for the regulation. The LDO was oversized to avoid severe damage. A survey of the evolution of yield before and after aging was done using Mundea WICKED tool.The jitter noise and lock time of the PLL are not affected by aging and the PLL itself corrects any degradations and deviations of its output parameters. For this, an investigation of one of its important blocks, the VCO, was made. Measurement results at 125 ° C show that the oscillation frequency of the VCO has undergone significant degradation. While the relative phase noise has not been impacted.The aging effect on the digital analog converter SAR-ADC consisting of 16 TI-ADCs has occurred. Extraction of static and dynamic performances showed a significant degradation of the SNR. In order to identify the block responsible for this degradation, simulations of a single ADC were made. Aging has negligible impact on the switches while the comparator was identified as the most sensitive block. Aging impacts the time windows for each sub-block of the comparator which gives rise to a false decision of one of these blocks, hence a false signal at the output of the comparator, resulting in a code error and a degradation in the performance of the ADC.Investigation of the aging effect on the power amplifier has shown a significant degradation of the PA figures of merit under the effect of RF stress. These impairments are due to the degradation of transistor parameters such as transconductance gm and resistor rds. A solution for improving these degradations has been proposed. Based on the principle of detection and adaptive polarization, this technique makes it possible to change the polarization of the PA in order to bring the degraded performances to their fresh value.Based on this research, it is possible to conclude that the aging mechanisms of the 28nmFDSOI CMOS technology are not a major obstacle to the development of analogue and mixed signal systems. However, a careful analysis of the effects of aging at the circuit level, from the design phase, using the models developed at the transistor level and included in the simulators, is necessary.The incorporation of effective detection and performance enhancement solutions is possible for the implementation of extremely precise circuits
