This book was released on 2003 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boom of mobile communications leads to an increasing request of low cost and low power mixed mode integrated circuits. Maturity of SOI technology, and recent progresses of MOSFET's microwave performances, explain the success of silicon as compared to III-V technologies for low-cost multigigahertz analog applications. The design of efficient circuits requires accurate, wide-band models for both active and passive elements. Within this frame, passive and active components fabricated in SOI technologies have been studied. Various topologies of integrated transmission lines, like Coplanar Waveguides or thin film microstrip lines, have been analyzed. Also, a new physical model of integrated inductors has been developed. This model, based on a coupled line analysis of square spiral inductors, is scalable and independent of the technology used. Inductors with various spacing between strips, conductor widths, or number of turns can be simulated on different multi-layered substrates. Each layer that composes the substrate is defined using its electrical properties (permittivity, permeability, conductivity). The performances of integrated sub-micron MOSFETs are analyzed. New alternative structures of transistor (the Graded Channel MOSFET and the Dynamic Threshold MOSFET) are proposed to increase the performances of a CMOS technology for for analog, low power, low voltage, and microwave applications. They are studied from Low to High frequency. The graded channel MOSFET is an asymmetric doped channel MOSFET's which bring solutions for the problems of premature drain break-down, hot carrier effects, and threshold voltage (Vth) roll-off issues in deep submicrometer devices. The GCMOS processing is fully compatible with the conventional SOI MOSFET process flow, with no additional steps needed. The dynamic threshold voltage MOS is a MOS transistor for which the gate and the body channel are tied together. All DTMOS electrical properties can be deduced from standard MOS theory by introducing Vbs = Vgs. The main advantage of DTMOS over conventional MOS is its higher drive current at low bias conditions. To keep the body to source current as low as possible, the body bias voltage must be kept lower than 0.7 V. It seems obvious that the DTMOS transistor is an attractive component for low voltage applications.

Available in PDF, EPUB and Kindle. Book excerpt: CMOS technology has now reached a state of evolution, in terms of both frequency and noise, where it is becoming a serious contender for radio frequency (RF) applications in the GHz range. Cutoff frequencies of about 50 GHz have been reported for 0.18 µm CMOS technology, and are expected to reach about 100 GHz when the feature size shrinks to 100 nm within a few years. This translates into CMOS circuit operating frequencies well into the GHz range, which covers the frequency range of many of today's popular wireless products, such as cell phones, GPS (Global Positioning System) and Bluetooth. Of course, the great interest in RF CMOS comes from the obvious advantages of CMOS technology in terms of production cost, high-level integration, and the ability to combine digital, analog and RF circuits on the same chip. This book discusses many of the challenges facing the CMOS RF circuit designer in terms of device modeling and characterization, which are crucial issues in circuit simulation and design.

This book was released on 2012-12-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is true that the Metal-Oxide-Semiconductor Field-Eeffect Transistor (MOSFET) is a key component in modern microelectronics. It is also true that there is a lack of comprehensive books on MOSFET characterization in gen eral. However there is more than that as to the motivation and reasons behind writing this book. During the last decade, device physicists, researchers and engineers have been continuously faced with new elements which made the task of MOSFET characterization more and more crucial as well as difficult. The progressive miniaturization of devices has caused several phenomena to emerge and modify the performance of scaled-down MOSFETs. Localized degradation induced by hot carrier injection and Random Telegraph Signal (RTS) noise generated by individual traps are examples of these phenomena. Therefore, it was inevitable to develop new models and new characterization methods or at least adapt the existing ones to cope with the special nature of these new phenomena. The need for more deep and extensive characterization of MOSFET param eters has further increased as the applications of this device have gained ground in many new fields in which its performance has become more and more sensi tive to the properties of its Si - Si0 interface. MOS transistors have crossed 2 the borders of high speed electronics where they operate at GHz frequencies. Moreover, MOSFETs are now widely employed in the subthreshold regime in neural circuits and biomedical applications.

Download or read book Compact Modeling written by Gennady Gildenblat and published by Springer Science & Business Media. This book was released on 2010-06-22 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the recent texts on compact modeling are limited to a particular class of semiconductor devices and do not provide comprehensive coverage of the field. Having a single comprehensive reference for the compact models of most commonly used semiconductor devices (both active and passive) represents a significant advantage for the reader. Indeed, several kinds of semiconductor devices are routinely encountered in a single IC design or in a single modeling support group. Compact Modeling includes mostly the material that after several years of IC design applications has been found both theoretically sound and practically significant. Assigning the individual chapters to the groups responsible for the definitive work on the subject assures the highest possible degree of expertise on each of the covered models.
Download or read book Tradeoffs and Optimization in Analog CMOS Design written by David Binkley and published by John Wiley & Sons. This book was released on 2008-09-15 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog CMOS integrated circuits are in widespread use for communications, entertainment, multimedia, biomedical, and many other applications that interface with the physical world. Although analog CMOS design is greatly complicated by the design choices of drain current, channel width, and channel length present for every MOS device in a circuit, these design choices afford significant opportunities for optimizing circuit performance. This book addresses tradeoffs and optimization of device and circuit performance for selections of the drain current, inversion coefficient, and channel length, where channel width is implicitly considered. The inversion coefficient is used as a technology independent measure of MOS inversion that permits design freely in weak, moderate, and strong inversion. This book details the significant performance tradeoffs available in analog CMOS design and guides the designer towards optimum design by describing: An interpretation of MOS modeling for the analog designer, motivated by the EKV MOS model, using tabulated hand expressions and figures that give performance and tradeoffs for the design choices of drain current, inversion coefficient, and channel length; performance includes effective gate-source bias and drain-source saturation voltages, transconductance efficiency, transconductance distortion, normalized drain-source conductance, capacitances, gain and bandwidth measures, thermal and flicker noise, mismatch, and gate and drain leakage current Measured data that validates the inclusion of important small-geometry effects like velocity saturation, vertical-field mobility reduction, drain-induced barrier lowering, and inversion-level increases in gate-referred, flicker noise voltage In-depth treatment of moderate inversion, which offers low bias compliance voltages, high transconductance efficiency, and good immunity to velocity saturation effects for circuits designed in modern, low-voltage processes Fabricated design examples that include operational transconductance amplifiers optimized for various tradeoffs in DC and AC performance, and micropower, low-noise preamplifiers optimized for minimum thermal and flicker noise A design spreadsheet, available at the book web site, that facilitates rapid, optimum design of MOS devices and circuits Tradeoffs and Optimization in Analog CMOS Design is the first book dedicated to this important topic. It will help practicing analog circuit designers and advanced students of electrical engineering build design intuition, rapidly optimize circuit performance during initial design, and minimize trial-and-error circuit simulations.

Download or read book All Digital Frequency Synthesizer in Deep Submicron CMOS written by Robert Bogdan Staszewski and published by John Wiley & Sons. This book was released on 2006-09-22 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new and innovative paradigm for RF frequency synthesis and wireless transmitter design Learn the techniques for designing and implementing an all-digital RF frequency synthesizer. In contrast to traditional RF techniques, this innovative book sets forth digitally intensive design techniques that lead the way to the development of low-cost, low-power, and highly integrated circuits for RF functions in deep submicron CMOS processes. Furthermore, the authors demonstrate how the architecture enables readers to integrate an RF front-end with the digital back-end onto a single silicon die using standard ASIC design flow. Taking a bottom-up approach that progressively builds skills and knowledge, the book begins with an introduction to basic concepts of frequency synthesis and then guides the reader through an all-digital RF frequency synthesizer design: Chapter 2 presents a digitally controlled oscillator (DCO), which is the foundation of a novel architecture, and introduces a time-domain model used for analysis and VHDL simulation Chapter 3 adds a hierarchical layer of arithmetic abstraction to the DCO that makes it easier to operate algorithmically Chapter 4 builds a phase correction mechanism around the DCO such that the system's frequency drift or wander performance matches that of the stable external frequency reference Chapter 5 presents an application of the all-digital RF synthesizer Chapter 6 describes the behavioral modeling and simulation methodology used in design The final chapter presents the implementation of a full transmitter and experimental results. The novel ideas presented here have been implemented and proven in two high-volume, commercial single-chip radios developed at Texas Instruments: Bluetooth and GSM. While the focus of the book is on RF frequency synthesizer design, the techniques can be applied to the design of other digitally assisted analog circuits as well. This book is a must-read for students and engineers who want to learn a new paradigm for RF frequency synthesis and wireless transmitter design using digitally intensive design techniques.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Analog Circuit Design written by Willy M.C. Sansen and published by Springer Science & Business Media. This book was released on 1999-10-31 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Analog Circuit Design concentrates on three topics: (X)DSL and other communication systems; RF MOST models; and integrated filters and oscillators. The book comprises five chapters on the first topic with six each on the other two, all written by internationally recognized experts. They are tutorial in nature and together make a substantial contribution to improving the design of analog circuits. The book is divided into three parts: Part I: (X)DSL and other Communication Systems presents some examples of recent improved modem techniques which have resulted in much higher transmission speeds over the local telephone network. It also presents components for the implementation of different standards. Part II: RF MOST Models investigates the state of the art in RF MOST models. It compares the existing BSIM3v3, Philips' Model 9 and the EKV model with respect to their capability to accurately predict GHz performance with submicron CMOST technologies. It shows how it has now become quite feasible to model a MOST at very high frequencies, giving rise to an increased use of MOST technologies in RF applications. Part III: Integrated Filters and Oscillators illustrates how the increasing use of communication tools goes hand-in-hand with the design of analog filters and oscillators with greater flexibility and higher bandwidth.
Download or read book Mosfet Modeling For Circuit Analysis And Design written by Carlos Galup-montoro and published by World Scientific. This book was released on 2007-02-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book dedicated to the next generation of MOSFET models. Addressed to circuit designers with an in-depth treatment that appeals to device specialists, the book presents a fresh view of compact modeling, having completely abandoned the regional modeling approach.Both an overview of the basic physics theory required to build compact MOSFET models and a unified treatment of inversion-charge and surface-potential models are provided. The needs of digital, analog and RF designers as regards the availability of simple equations for circuit designs are taken into account. Compact expressions for hand analysis or for automatic synthesis, valid in all operating regions, are presented throughout the book. All the main expressions for computer simulation used in the new generation compact models are derived.Since designers in advanced technologies are increasingly concerned with fluctuations, the modeling of fluctuations is strongly emphasized. A unified approach for both space (matching) and time (noise) fluctuations is introduced.
