Design of Very High-Frequency Multirate Switched-Capacitor Circuits presents the theory and the corresponding CMOS implementation of the novel multirate sampled-data analog interpolation technique which has its great potential on very high-frequency analog frond-end filtering due to its inherent dual advantage of reducing the speed of data-converters and DSP core together with the specification relaxation of the post continuous-time filtering. This technique completely eliminates the traditional phenomenon of sampled-and-hold frequency-shaping at the lower input sampling rate. Also, in order to tackle physical IC imperfections at very high frequency, the state-of-the-art circuit design and layout techniques for high-speed Switched-Capacitor (SC) circuits are comprehensively discussed: -Optimum circuit architecture tradeoff analysis -Simple speed and power trade-off analysis of active elements -High-order filtering response accuracy with respect to capacitor-ratio mismatches -Time-interleaved effect with respect to gain and offset mismatch -Time-interleaved effect with respect to timing-skew and random jitter with non-uniformly holding -Stage noise analysis and allocation scheme -Substrate and supply noise reduction -Gain-and offset-compensation techniques -High-bandwidth low-power amplifier design and layout -Very low timing-skew multiphase generation Two tailor-made optimum design examples in CMOS are presented. The first one achieves a 3-stage 8-fold SC interpolating filter with 5.5MHz bandwidth and 108MHz output sampling rate for a NTSC/PAL CCIR 601 digital video at 3 V. Another is a 15-tap 57MHz SC FIR bandpass interpolating filter with 4-fold sampling rate increase to 320MHz and the first-time embedded frequency band up-translation for DDFS system at 2.5V. The corresponding chip prototype achieves so far the highest operating frequency, highest filter order and highest center frequency with highest dynamic range under the lowest supply voltage when compared to the previously reported high-frequency SC filters in CMOS.

After an overview of major scientific discoveries of the 18th and 19th centuries, which created electrical science as we know and understand it and led to its useful applications in energy conversion, transmission, manufacturing industry and communications, this Circuits and Systems History book fills a gap in published literature by providing a record of the many outstanding scientists, mathematicians and engineers who laid the foundations of Circuit Theory and Filter Design from the mid-20th Century. Additionally, the book records the history of the IEEE Circuits and Systems Society from its origins as the small Circuit Theory Group of the Institute of Radio Engineers (IRE), which merged with the American Institute of Electrical Engineers (AIEE) to form IEEE in 1963, to the large and broad-coverage worldwide IEEE Society which it is today. This second edition, commemorating the 75th anniversary of the Circuits and Systems Society, builds upon the first edition's success by expanding the scope of specific chapters, introducing new topics of relevance, and integrating feedback from readers and experts in the field, reflecting the evolving landscape of Circuits and Systems alongside the evolution of the professional society. Many authors from many countries contributed to the creation of this book, working to a very tight time schedule. The result is a substantial contribution to their enthusiasm and expertise, which it is hoped readers will find both interesting and useful. It is certain that in such a book, omission will be found, and in the space and time available, much valuable material had to be left out. It is hoped that this book will stimulate an interest in the marvelous heritage and contributions of the many outstanding people who worked in the Circuits and Systems area.

Analog-to-Digital Converters (ADCs) play an important role in most modern signal processing and wireless communication systems where extensive signal manipulation is necessary to be performed by complicated digital signal processing (DSP) circuitry. This trend also creates the possibility of fabricating all functional blocks of a system in a single chip (System On Chip - SoC), with great reductions in cost, chip area and power consumption. However, this tendency places an increasing challenge, in terms of speed, resolution, power consumption, and noise performance, in the design of the front-end ADC which is usually the bottleneck of the whole system, especially under the unavoidable low supply-voltage imposed by technology scaling, as well as the requirement of battery operated portable devices. Generalized Low-Voltage Circuit Techniques for Very High-Speed Time-Interleaved Analog-to-Digital Converters will present new techniques tailored for low-voltage and high-speed Switched-Capacitor (SC) ADC with various design-specific considerations.

High-speed Photodiodes in Standard CMOS Technology describes high-speed photodiodes in standard CMOS technology which allow monolithic integration of optical receivers for short-haul communication. For short haul communication the cost aspect is important , and therefore it is desirable that the optical receiver can be integrated in the same CMOS technology as the rest of the system. If this is possible then ultimately a singe-chip system including optical inputs becomes feasible, eliminating EMC and crosstalk problems, while data rate can be extremely high. The problem of photodiodes in standard CMOS technology it that they have very limited bandwidth, allowing data rates up to only 50Mbit per second. High-speed Photodiodes in Standard CMOS Technology first analyzes the photodiode behaviour and compares existing solutions to enhance the speed. After this, the book introduces a new and robust electronic equalizer technique that makes data rates of 3Gb/s possible, without changing the manufacturing technology. The application of this technique can be found in short haul fibre communication, optical printed circuit boards, but also photodiodes for laser disks.

IGH-SPEED Digital to Analog (D/A) converters are essential components in digi- Htal communication systems providing the necessary conversion of signals encoding information in bits to signals encoding information in their amplitude vs. time domain characteristics. In general, they are parts of a larger system, the interface, which c- sists of several signal conditioning circuits. Dependent on where the converter is located within the chain of circuits in the interface, signal processing operations are partitioned in those realized with digital techniques, and those with analog. The rapid evolution of CMOS technology has established implicit and explicite trends related to the interface, and in particular to the D/A converter. The implicit relationship comes via the growth of digital systems. First, it is a global trend with respect to all interface circuits that increasing operating frequencies of digital systems place a similar demand for the interface circuits. The second trend takes place locally within the int- face. Initially, the D/A converter was placed at the beginning of the interface chain, and all signal conditioning was implemented in the analog domain after the D/A conversion. The increasing ?exibility and robustness of digital signal processing shifted the D/A converter closer to the end point of the chain where the demands for high quality high frequency operation are very high.

Current-mode circuits, where information is represented by the branch currents of the circuits rather than the nodal voltages as of voltage-mode circuits, possess many unique and attractive characteristics over their voltage-mode counterparts including a small nodal time constant, high current swing in the presence of a low supply voltage, reduced distor tion, a low input impedance, a high output impedance, less sensitive to switching noise, and better ESD immunity. CMOS current-mode circuits have found increasing applications in telecommunication sys tems, instrumentation, analog signal processing, multiprocessors, high speed computer interfaces, and the backplane of complex electronic sys tems. This book deals with the analysis and design of continuous-time CMOS current-mode circuits for data communications over wire chan nels. CMOS current-mode sampled-data networks, such as switch- current circuits, and current-mode logic circuits, are excluded. The book is organized as the followings : Chapter 1 examines the distinct characteristics of ideal voltage-mode and current-mode circuits. The topology duaUty of these two classes of circuits is investigated using the concept of inter-reciprocity and adjoint network. A critical comparison of the input and output impedances, bandwidth, slew rate, propagation delay, signal swing, supply voltage sensitivity, and ESD sensitivity of voltage-mode and current-mode cir cuits is provided. Chapter 2 investigates design techniques that improve the perfor mance of low-voltage current-mode circuits including input impedance reduction, output impedance boosting, bandwidth enhancement, mis match compensation, power consumption reduction, and swing improve ment. Chapter 3 investigates the modeling of wire channels.
