Abstract (sommario):

Two new active-only sinusoidal oscillator circuits are proposed. The first circuit uses one current feedback operational amplifier (CFOA) and four operational transconductance amplifiers (OTAs). The second circuit uses only four OTAs. Without using any external passive elements, voltage (or current) control of the frequency and condition of oscillation, of the two circuits, can be achieved by adjusting the bias currents of the OTAs. The proposed circuits enjoy low sensitivities.

Abstract (sommario):

Purpose The ammeter can measure the direct current and low-frequency alternating current through the wires, but it is difficult to measure complex waveforms. The oscilloscope can measure complex waveforms, but it is easy to measure the voltage waveform and difficult to measure the current waveform. Thus, how to measure complex current waveforms with oscilloscope is an important and crucial issue that needs to be solved in practical engineering applications. To solve the above problems, an active short circuit line method is proposed to measure the volt-ampere characteristic curve of chaotic circuits. Design/methodology/approach In this paper, an active short circuit line method is proposed to measure the volt-ampere characteristic curve of various chaotic circuits especially for memristive systems. A memristor-based chaotic system is introduced, and the corresponding memristor-based circuit is constructed and implemented by using electronic components. Findings The chaotic attractors and volt-ampere characteristic curve of the memristor-based chaotic circuit are successfully analyzed and verified by oscilloscope measurement with the proposed active short circuit line method. Accordingly, the hardware circuit experiments are carried out to validate the effectiveness and feasibility of the active short circuit line method for these chaotic circuits. A good agreement is shown between the numerical simulations and the experimental results. Originality/value The primary contributions of this paper are as follows: an active short circuit line method for measuring the volt-ampere characteristic curve of chaotic circuits is proposed for the first time. A memristor-based chaotic system is also constructed by using memristor as nonlinear term. Then, the active short circuit line method is applied to measure the volt-ampere characteristic curve of the corresponding memristor-based chaotic circuit.

Abstract This paper provides an innovative practical realization of a memristor based chaotic circuit. The first part discusses the mathematical analysis of the proposed system, including calculation of an eigenvalues, bifurcation diagram and largest Lyapunov exponents. Another parts deal with circuitry realization and the influence of parasitic properties of active elements. The circuit simulations obtained by PSpice environment and the practical measurement results on a breadboard are presented in the last part of this paper. The main aim of this work is an innovative realization of the memristor based chaotic circuit with one type of energy-storage element (linear passive capacitor) and with simpler construction in comparison to other circuits. The next contribution consists in verification of designed circuit with respect to influence of parasitic properties of active elements to chaos destruction.

Abstract (sommario):

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 (sommario):

Electrically small antenna suffer from the high Q impedance such as narrow bandwidth and poor gain. To improve them, passive impedance matching is often used but it is restricted to a Bode-Fano limit. To skip it, active matching incorporating non-Foster circuits can provide a good solution. Using non-Foster theory, in this paper an active reactance circuit (ARC) design is proposed for application to electrically small antenna prototypes.

A feedback circuit for an Organic Light Emitting Diode (OLED) based display is proposed and demonstrated. An OLED-based flat panel display is brighter, much lower power, has no viewing angle limitation and potentially cheaper compared to available Liquid Crystal (LC) based displays. Despite these advantages, an OLED-based display is not widely commercialized mainly due to its short practical lifetime. The I-V characteristics of the individual OLED pixels vary over time, temperature and processing-dependent parameters. Moreover, the variation is not uniform across an array of OLED pixels, causing OLED based displays to lose brightness accuracy after a few thousand hours of operation. The proposed feedback circuit is used to compensate for the non-uniformities in the individual OLED characteristics. The resulting display leverages the beneficial aspects of OLED display technology, while maintaining pixel uniformity and grayscale reproducibility. A demonstration system is built proving the feasibility of a flat panel display using direct optical feedback. The feedback loop monitors the output light level using a sensor and adjusts the current fed to the pixels to set the output light power to a digitally set reference level. The system shares a single feedback loop among a number of pixels, saving power and real estate. The demonstration system consists of a 5x5 array of LEDs, a CMOS camera, analog pixel circuitry, driver and feedback loop, as well as a digital controller. The demonstration system also shows the feasibility of time-sharing a feedback loop among a number of output devices.

Abstract (sommario):

Two computer-aided design methods are described in this dissertation for the design of Thermionic Integrated Circuits (TIC). Such circuits combine vacuum tube techniques with modern integrated circuit techniques to produce microminiature vacuum tube circuits, with possibly hundreds of vacuum triodes on a single substrate. The first method described in the line charge approximation technique in which the TIC devices are modelled as collections of line charges. A TIC is produced by evaporating metal electrodes on one or two sapphire substrates. The entire structure is heated to about 850°C so that electrons are emitted from the cathode electrodes to travel to the plate electrodes as in a conventional vacuum triode. The line charge approximation method is easy to implement and provides a simple means of satisfying the sapphire dielectric boundary conditions of the TIC basic problems, which are electrostatics problems since space charge effects are neglected. The method requires only a single matrix inversion and is a finite element Green's function approach. The method uses no iteration as in previous TIC analysis methods. Later as the development of TIC devices proceeded further it was found that conducting shields had to be placed over the unused sapphire surface so that the basic problem became a metal box problem. For this case a second method was developed called the step and ramp function method in which each electrode is modelled by a step function, which is the electric field solution for a potential step on a zero potential boundary. A superposition of these step functions models the TIC electrodes. The method provides direct calculation of the electric fields from equations and requires no iteration or matrix inversion. The potential variation between electrodes is modelled by linear potential functions called ramps. A superposition of steps and ramps completely specifies a TIC structure. The method does not solve for the case of electrodes which are elevated above substrates. For this case a modified line charge method was developed but not implemented.

Abstract (sommario):

Researchers at Uppsala University are developing a flywheel energy storage device intended to be used in electrical vehicles. Kinetic energy storage technology has potential to make purely electric powertrain both more effective and efficient. While deployment of the third prototype is approaching there has been a request for a more precise and noise-immune circuitry to power active magnetic bearings that hold and stabilise the rotor. A similar circuit designed for powering electromagnets was recently developed at the Uppsala University’s Electricity department and is used as a template in development of the new active magnetic bearing driver circuit. Current measurement integration technique is tested and implemented as a way to increase circuit’s control feedback loop performance. To further boost precision and noise-immunity 0-20 mA current loop signals are adapted as the standard for output signals. Results of this project include a thorough analysis of the electromagnet driver circuit development, implementation of a new current sensing technique including an experimental self-inductance measurement, printed circuit board layout design and a full list of components necessary to power and control two sets of active magnetic bearings consisting of 8 individual electromagnets.

Abstract (sommario):

During AC-DC conversion, the ripple power at the input of the converter must be filtered from the output. This filtering can be easily done by placing a capacitor on the DC bus. For systems with power output of hundreds of Watts or more, this capacitor must be quite high to effectively perform the filtering, and in order to be cost effective, an aluminum electrolytic capacitor (Al e-caps) needs to be used. The lifespan of Al e-caps is notoriously short, so for long lifespan systems, their use is not advisable. Film capacitors have longer lifespans than Al e-caps but are more expensive on a cost per Farad basis. Methods have been proposed to reduce the required capacitance so that film capacitors can be cost effectively used. One of these methods is to use a separate decoupling port in the circuit that can filter the ripple power without the limitation of being connected directly to the DC bus. The first contribution is a method of using an active power decoupling (APD) port with a buck-based circuit that does not require direct measurement of the AC input signal for controlling the ripple power to the port. This APD port requires only two extra switches and some simple signal processing circuitry to generate a reference signal and control the voltage to the APD port capacitor. The second contribution is a design guide for a sliding mode control (SMC) system for the APD port. SMC shows promise as a control system for power electronics circuits and has never been demonstrated on an APD port before. The proposed circuit and control system is used in a 700 Watt AC-DC converter with power factor correction and is compared in simulation to a benchmark converter using a passive capacitor on the DC bus. The capacitance is reduced from 300μF to a 35μF and a 75μF capacitor without any effect on performance as indicated by measures of the voltage ripple, power factor and total harmonic distortion. The capacitance reduction results in a cost savings of $175 on capacitors when using prices that were current at time of publication.

Abstract (sommario):

The high market demand for power electronics converters nowadays requires converters with high power quality, great reliability and low cost. However, there are several challenges related to these systems, one relevant example is the energy ripple in the DC bus for single phase converters which causes problems such as overheating and reduction of the capacitor lifetime. To limit this energy ripple, which consists of the second order harmonic in the DC bus, a bulky DC link capacitor is usually required. Although, it results in low power density and large converter volume. Some of these capacitors can also present some problems such as shorter life-time and reliability. This thesis addresses this problem by adding active filter storage elements to the DC bus to absorb the pulsating power at twice the frequency on the bus line. In this way, there is no need to increase in the capacitor size to reduce the ripple. On the contrary, this method allows to replace the DC capacitor used for the conventional method by two smaller capacitors. The size of the DC bus capacitor is reduced, as is the energy ripple, and thereby the power density is increased. Besides, with the significant improvement of power semiconductor devices nowadays, the storage element method can be applied with acceptable cost and high reliability. In this thesis, component design and ripple analysis are explained in detail. The effectiveness of the power storage method is confirmed by simulations.
Dagens höga efterfrågan på kraftelektronikbaserade omvandlare kräver hög kvalitet, hög tillförlitlighet och låg kostnad. Det finns dock flera utmaningar för dessa system. Ett relevant exempel är energivariationer i DC-bussen hos enfas-omvandlare. Variationerna kan orsaka problem som överhettning och minskning av kondensatorernas livslängd.Variationerna, som är en andra ordningens överton av den fundamentala frekvensen, begränsas vanligen med en skrymmande kondensator kopplad till DC-bussen. Det resulterar i låg effekttäthet och stor omvandlarvolym. Några av dessa kondensatorer kan också medföra problem med kortare livslängd och lägre tillförlitlighet.I denna rapport behandlas detta problem genom att lägga till ett aktivt filter med effektlager vid DC-bussen för att absorbera den andra övertonen. Därmed behövs ingen ökning av kondensatorns storlek för att absorbera den andra övertonen. Den konventionella DC-busskondensatorn kan istället ersättas med två mindre kondensatorer.När både kondensatorns storlek och övertonen minskas fås högre effekttäthet som konsekvens. Med den senaste tidens utveckling inom halvledarkomponenter kan metoden dessutom implementeras med hög tillförlitlighet till en rimlig kostnad.Komponenternas utformning och analysen av variationerna i DC-bussen förklaras i detalj i denna avhandling. Funktionen hos metoden bekräftas av simuleringar.

Abstract (sommario):

Although known to chemists for nearly a century, interlocked structures have only been synthetically accessible since the 1980s when 'passive template' methods allowed the pre-complexation of components to increase yields. 'Active template' methods, initially developed by the Leigh group in 2006, have resulted in even higher yields of rotaxanes - "interlocked structures formed of at least one macrocycle penetrated by at least one impassably-stoppered axle" - and a phenomenal surge in interest in their properties as a result of this increased availability. This first method adapted highly efficient 'click' methodology to give the Active Template Copper-Mediated Alkyne-Azide Cycloaddition reaction (AT-CuAAC) and is still the most used rotaxane-forming method today. In this work, I provide the reader with an overview of these mechanically-interlocked architectures from synthesis to application. Later work by the Goldup group showed that a smaller macrocycle could make [2]rotaxanes (one macrocycle, one axle) with complete efficiency compared to their larger forebears, while intermediate sizes gave incomplete conversion, with unused macrocycle unrecovered. In this investigation, I then identify a series of novel doubly-interlocked [3]rotaxane products from this reaction that explain the absence of unused macrocycle. I then explore the variation of conditions and show how these novel products are favoured by high temperatures and high catalyst loading in a non-coordinating solvent, whereas their yields are suppressed in low temperatures and catalyst loading in a co-ordinating solvent with base, giving up to quantitative [2]rotaxane formation. To provide a mechanistic rationale for the formation of these products I then assess the effects of stopper length, macrocycle structure and lithiation experiments on the ratio of the [2]- to [3]rotaxane. The results of the above allow me to derive a new mechanistic hypothesis when I then test in a series of experiments to form [3]rotaxanes with two rings differing in either structure, size or both. Finally, the design, synthesis and testing of a stopper developed and used by myself for the AT-CuAAC reaction is described such that where two macrocycles differ in size, the larger can only be held in a novel heterocircuit [3]rotaxane, produced in synthetically useful yields.

Abstract (sommario):

This thesis presents the analysis and characterization of a low sensitivity dual feedback active RC bandpass filter. Chapter 2 details the analysis of the network and a method of simplifying the resultant transfer function by a single pole/zero cancellation. Chapter 3 characterizes the simplified transfer function through an analysis of the quality factor and of the center frequency gain as functions of the individual variables of the circuit. It also details sensitivity analyses of these characteristic quantities and a stability analysis. Lastly, chapter 3 presents graphical representations of the equations developed so that they can be used as design tools. It then goes through the details of applying these graphs to an example network. Chapter 4 explains the differences between experimental data and predicted data by discussing some of the nonlinearities neglected in the original analysis. Finally chapter 5 restates the design technique in light of the predominant nonlinearities.

Abstract (sommario):

Abstract In today's electronic industry of shrinking circuit boards and shrinking semiconductor integrated circuits (IC), semiconductor companies have to be creative in providing devices with more circuitry on less silicon. Copper Bond over Active Circuit (BOAC)/Copper over Anything (COA) processes allow routing and bonding to thick top level metallization on the LinBiCMOS technology node. This paper discusses failure analysis (FA) techniques and approaches on un-passivated BOAC, and explains a generic BOAC/COA process. The approach to FA of BOAC involves package inspection-non intrusive analysis, decapsulation, die inspection, and defect identification/root cause analysis. Case studies are presented to explain the specific FA steps. Fault isolation involving BOAC requires the strategic removal of copper traces and selective analysis of the failed circuitry. Liquid crystal and micro-probing have been used effectively in failure isolation.

Abstract (sommario):

In this paper, we present a new model for an organic pixel addressing circuit based on four-transistor configuration. The proposed circuit doesn’t have the problems of regular configurations which are based on four-thin film transistors (TFT). Circuits based on four-TFT have many advantages, but the only problem is the existence of current peaks at the beginning of each pixel luminescence. Both 4-TFT based configuration and proposed one were simulated using HSPICE. Simulation results indicate the superiority of the proposed method compared with existing technique.
