Book excerpt: The area of analog integrated circuits is facing some serious challenges due to the ongoing trends towards low supply voltages, low power consumption and high-frequency operation. The situation is becoming even more complicated by the fact that many transfer functions have to be tunable or controllable. A promising approach to facing these challenges is given by the class of dynamic translinear circuits, which are, as a consequence, receiving increasing interest. Several different names are used in literature: log-domain, exponential state-space, current-mode companding, instantaneous companding, tanh-domain, sinh-domain, polynomial state-space, square-root domain and translinear filters. In fact, all these groups are (overlapping) subclasses of the overall class of dynamic translinear circuits. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is a compilation of research findings in this growing field. It comprises ten contributions, coming from recognized `dynamic-translinear' researchers in Europe and North America. Research Perspectives on Dynamic Translinear and Log-Domain Circuits is an edited volume of original research.

This book was released on 2007-05-08 with total page 1065 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the frequency of communication systems increases and the dimensions of transistors are reduced, more and more stringent performance requirements are placed on analog circuits. This is a trend that is bound to continue for the foreseeable future and while it does, understanding performance trade-offs will constitute a vital part of the analog design process. It is the insight and intuition obtained from a fundamental understanding of performance conflicts and trade-offs, that ultimately provides the designer with the basic tools necessary for effective and creative analog design. Trade-offs in Analog Circuit Design, which is devoted to the understanding of trade-offs in analog design, is quite unique in that it draws together fundamental material from, and identifies interrelationships within, a number of key analog circuits. The book covers ten subject areas: Design methodology, Technology, General Performance, Filters, Switched Circuits, Oscillators, Data Converters, Transceivers, Neural Processing, and Analog CAD. Within these subject areas it deals with a wide diversity of trade-offs ranging from frequency-dynamic range and power, gain-bandwidth, speed-dynamic range and phase noise, to tradeoffs in design for manufacture and IC layout. The book has by far transcended its original scope and has become both a designer's companion as well as a graduate textbook. An important feature of this book is that it promotes an intuitive approach to understanding analog circuits by explaining fundamental relationships and, in many cases, providing practical illustrative examples to demonstrate the inherent basic interrelationships and trade-offs. Trade-offs in Analog Circuit Design draws together 34 contributions from some of the world's most eminent analog circuits-and-systems designers to provide, for the first time, a comprehensive text devoted to a very important and timely approach to analog circuit design.

This book was released on 2022-09-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the requirements for low power consumption and very small physical dimensions in portable, wearable and implantable medical devices are calling for integrated circuit design techniques using MOSFETs operating in the subthreshold regime, this book first revisits some well-known circuit techniques that use CMOS devices biased in subthreshold in order to establish nanopower integrated circuit designs. Based on the these findings, this book shows the development of a class-AB current-mode sample-and-hold circuit with an order of magnitude improvement in its figure of merit compared to other state-of-the-art designs. Also, the concepts and design procedures of 1) single-branch filters 2) follower-integrator-based lowpass filters and 3) modular transconductance reduction techniques for very low frequency filters are presented. Finally, to serve the requirement of a very large signal swing in an energy-based action potential detector, a nanopower class-AB current-mode analog multiplier is designed to handle input current amplitudes of more than 10 times the bias current of the multiplier circuit. The invented filter circuits have been fabricated in a standard 0.18 μ CMOS process in order to verify our circuit concepts and design procedures. Their experimental results are reported.

This book was released on 2006-04-18 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on my doctoral thesis at the Helsinki University of Technology. Several different projects during five years guided me from the basics of the RF IC design to the implementations of highly integrated radio receiver chips. Sharing time and effort between IC and system issues is not always straightforward. I have been lucky to follow both topics and share experiences with diligent and enthusiastic people having different specialities. As a result, this book will cover a wide range of different topics needed in the design of highly integrated radio receivers. Experiences from the first receiver prototypes for the third generation cellular systems form the basis of this book. Most of the issues are directly related to the early proposals of European and Japanese standardization organizations. For example, the chip rate was originally set to 4. 096 Mcps in a wide-band CDMA channel. I have kept that number in the book in most of the examples although it has been later changed to 3. 84 Mcps. I hope that the readers will accept that and the possible other incompabilities to the latest specifications. At least in the research phase the changes even in the most essential requirements are definitely not a rare incident and IC designers should be able to react and modify their designs as soon as they can.

Available in PDF, EPUB and Kindle. Book excerpt: Operational Amplifiers - Theory and Design is the first book to present a systematic circuit design of operational amplifiers. Containing state-of-the-art material as well as the essentials, the book is written to appeal to both the experienced practitioner and the less initiated circuit designer. It is shown that the topology of all operational amplifiers can be divided into nine main overall configurations. These configurations range from one gain stage up to four or more gain stages. Many famous designs are evaluated in depth. High-frequency compensation techniques are presented for all nine configurations. Special emphasis is placed on low-power low-voltage architectures with rail-to-rail input and output ranges. Operational Amplifiers - Theory and Design also develops on the theme of the design of fully differential operational amplifiers and operational floating amplifiers. In addition, the characterization of operational amplifiers by macromodels and error matrices is presented, together with measurement techniques for their parameters. Carefully structured and enriched by numerous figures, problems and simulation exercises the book is ideal for the purposes of self-study and self-evaluation.

This book was released on 2012-12-06 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analog Test Signal Generation Using Periodic SigmaDelta-Encoded Data Streams presents a new method to generate high quality analog signals with low hardware complexity. The theory of periodic SigmaDelta-encoded bitstreams is presented along with a set of empirical tables to help select the appropriate parameters of a bitstream. An optimization procedure is also outlined to help select a bit sequence with the desired attributes. A large variety of signals can be generated using this approach. Silicon implementation issues are discussed with a specific emphasis on area overhead and ease of design. One FPGA circuit and three different silicon implementations are presented along with experimental results. It is shown that simple designs are capable of generating very high precision signals-on-chip. The technique is further extended to multi-bit signal generation where it is shown how to increase the performance of arbitrary waveform, generators commonly found in past and present-day mixed-signal testers. No hardware modifications are required, only the numbers in memory are changed. Three different calibration techniques to reduce the effects of the AWG's non-linearities are also introduced, together with supporting experimental evidence. The main focus of this text is to describe an area-efficient technique for analog signal generation using SigmaDelta-encoded data stream. The main characteristics of the technique are: High quality signals (SFDR of 110 dB observed); Large variety of signals generated; Bitstreams easily obtained with a fast optimization program; Good frequency resolution, compatible with coherent sampling; Simple and fast hardware implementation; Mostly digital, except an easily testable 1-bit DAC and possibly a reconstruction filter; Memory already available on-chip can be reused, reducing area overhead; Designs can be incorporated into existing CAD tools; High frequency generation.

Available in PDF, EPUB and Kindle. Book excerpt: Analog design still has, unfortunately, a flavor of art. Art can be beautiful. However, art in itself is difficult to teach to students and difficult to transfer from experienced analog designers to new trainee designers in companies. Structured Electronic Design: High-Performance Harmonic Oscillators and Bandgap References aims to systemize analog design. The use of orthogonalization of the design of the fundamental quality aspects (noise, distortion, and bandwidth) and hierarchy in the subsequent design steps, enables designers to achieve high-performance designs, in a relatively short time. As a result of the systematic design procedure, the effect of design decisions on the circuit performance is made clear. Additionally, the use of resources for reaching a specified performance is tracked. This book, therefore, describes the structured electronic design of high-performance harmonic oscillators and bandgap references. The structured design of harmonic oscillators includes the maximization of the carrier-to- noise ratio by means of tapping, i.e. an impedance adaption method for noise matching. The bandgap reference, a popular implementation of a voltage reference, is studied via the unusual concept of the linear combination of base-emitter voltages. The presented method leads to the design of high-performance references in CMOS and Bipolar technology. Using this concept, on a high level of abstraction the quality with respect to, for instance, noise and power-supply rejection can be identified. In this book, it is shown with several design examples that this method provides an excellent starting point for the design of high-performance bandgap references. Auxiliary to the harmonic-oscillator and bandgap reference design are the negative- feedback amplifiers. In this book the systematic design of the dynamic behavior is emphasized. By means of the identification of the dominant poles, it is possible to give an upper limit of the attainable bandwidth, even before the real frequency compensation is accomplished. Structured Electronic Design: High-Performance Harmonic Oscillators and Bandgap References is a valuable book for researchers and designers, as well as students in the field of analog design. It helps both the experienced and trainee designer to come to grips with the design of analog circuits. The presented method is illustrated by several well- described design examples.

Available in PDF, EPUB and Kindle. Book excerpt: The Analog to Digital Converters represent one half of the link between the world we live in - analog - and the digital world of computers, which can handle the computations required in digital signal processing. These devices are mathematically very complex due to their nonlinear behavior and thus fairly difficult to analyze without the use of simulation tools. High Speed A/D Converters: Understanding Data Converters Through SPICE presents the subject from the practising engineer's point of view rather than from the academic's point of view. A practical approach is emphasized. High Speed A/D Converters: Understanding Data Converters Through SPICE is intended as a learning tool by providing building blocks that can be stacked on top of each other to build higher order systems. The book provides a guide to understanding the various topologies used in A/D converters by suggesting simple methods for the blocks used in an A/D converter. The converters discussed throughout the book constitute a class of devices called undersampled or Nyquist converters. The tools used in deriving the results presented are: TopSpice® by Penzar - a mixed mode SPICE simulator - version 5.90. The files included in Appendix A were written for this tool. However, most circuit files need only minor adjustments to be used on other SPICE simulators such as PSpice, Hspice, IS_Spice and Micro-Cap IV; Mathcad 2000 - Professional by Mathsoft. This tool is very useful in performing FFT analysis as well as drawing some of the graphs. Again, the mathcad files are included to help the user analyze the data. High Speed A/D Converters: Understanding Data Converters Through SPICE not only supplies the models for the A/D converters for SPICE program but also describes the physical reasons for the converter's performance.
