Book Description
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.

Book Description
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.

Book Description
This book helps engineers to grasp fundamental theories and design principles by presenting physical and intuitive explanations of switched-capacitor circuits. Numerous circuit examples are discussed and the author emphasizes the most important and fundamental principles involved in implementing state-of-the-art switched-capacitor circuits for analog signal processing and power management applications. Throughout the book, the author presents numerous step-by-step tutorials and gives practical design examples.While some quantitative analysis is necessary to understand underlying concepts, tedious mathematical equations and formal proofs are avoided. An intuitive appreciation for switched-capacitor circuits is achieved.Much of the existing information on contemporary switched-capacitor circuit applications is in the form of applications notes and data sheets for various switched-capacitor ICs. This book compiles such information in a single volume and coherently organizes and structures it.The author has his own website at www.mingliangliu.com * Step-by-step tutorials which emphasize the most fundamental principals of switched-capacitor circuits * Few tedious mathematical equations * The first easy-to-understand compilation on this subject--most information available is not very cohesive

Book Description
The objective of the book is to provide sufficient background and understand ing to enable its readers to design and apply switched capacitor circuits whether these are to be implemented as discrete circuits or by MOS technol ogy. Since this is the first book devoted entirely to the subject of switched capacitor circuits, it has no pattern to follow. Fortunately, it was developed in an environment where many of the circuits and concepts it discusses could actually be integrated as MOS integrated circuits. It is hoped that this environ ment has created a selection process that has enhanced the contents. Switched capacitor circuits provide an example of the influence that technol ogy can have on the field of electrical engineering. Only seven years ago, the problem of building analog circuits and systems using standard MOS technology was still unsolved. Although analog circuits and systems were implemented by means of integrated circuit technology, they were neither economical nor competitive. The act of combining analog sampled data tech niques with MOS technology has solved this difficulty. As a result, the field of switched capacitor circuits has developed into maturity in a relatively short period of time.

Book Description
The realization of signal sampling and quantization at high sample rates with low power dissipation is an important goal in many applications, includ ing portable video devices such as camcorders, personal communication devices such as wireless LAN transceivers, in the read channels of magnetic storage devices using digital data detection, and many others. This paper describes architecture and circuit approaches for the design of high-speed, low-power pipeline analog-to-digital converters in CMOS. Here the term high speed is taken to imply sampling rates above 1 Mhz. In the first section the dif ferent conversion techniques applicable in this range of sample rates is dis cussed. Following that the particular problems associated with power minimization in video-rate pipeline ADCs is discussed. These include optimi zation of capacitor sizes, design of low-voltage transmission gates, and opti mization of switched capacitor gain blocks and operational amplifiers for minimum power dissipation. As an example of the application of these tech niques, the design of a power-optimized lO-bit pipeline AID converter (ADC) that achieves =1. 67 mW per MS/s of sampling rate from 1 MS/s to 20 MS/s is described. 2. Techniques for CMOS Video-Rate AID Conversion Analog-to-digital conversion techniques can be categorized in many ways. One convenient means of comparing techniques is to examine the number of "analog clock cycles" required to produce one effective output sample of the signal being quantized.
