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.

This book contains the extended and revised versions of the talks of all speakers presented at the sixth AACD Workshop held in Villa Olmo, April 2-4 1997 Como, Italy. The local chairman was Pietro Erratico and the organization was performed by Isabella De Quattro both of SGS- Thomson Microelectronics Cornareda and Agrate Brianza Italy. The program consisted of six tutorials per day during three days. These tutorials were presented by experts in the field to give state of the art information. Program topics for the following workshop are selected by the audience at the end of the workshop. The program committee, consisting of 10han Huijsing of Delft University of Technology, Willy Sansen of Katholieke Universiteit Leuven and Rudy van de Plassche of Philips Research Labs and University of Technology Eindhoven elaborates the selected topics into a three day program and selects the experts in the field for presentation. Each AACD Workshop has given rise to the publication of a book by Kluwer entitled "Analog Circuit Design".This series of six books in a row provides a valuable overview of all analog circuit techniques concerning design, CAD, simulation and device modeling and can be seen as a reference to those involved in analog circuits.
