Data Converters for Wireless Standards / Edition 1

by Chunlei Shi, Ismail Mohamed Mostafa

Overview

Wireless communication is witnessing tremendous growth with p- liferation of different standards covering wide, local and personal area networks (WAN, LAN and PAN). The trends call for designs that - low 1) smooth migration to future generations of wireless standards with higher data rates for multimedia applications, 2) convergence of wireless services allowing access to different standards from the same wireless device, 3) inter-continental roaming. This requires designs that work across multiple wireless standards, can easily be reused, achieve maximum hardware share at a minimum power consumption levels particularly for mobile battery-operated devices. All this calls for higher levels of system integration of both the radio and the digital baseband parts. It also calls for radio design solutions with mixed signal strategies that take full advantage of technology sca- down by moving functions, such as channel select filtering, modulation and demodulation, to the digital domain. Central to achieving these goals is the design of data converters for these emerging standards in the context of technology and market trends.

Editorial Reviews

Central to achieving the goals of smooth system integration across multiple wireless standards is the design of compatible data converters. Shi (Qualcomm CDMA Technologies) and Ismail (Analog VLSI Lab, Ohio State U.) present the design of such converters and introduce the underlying circuit design principles. After discussing radio transceiver architectures, the authors deal with power- optimized analog to digital converters and present an experimental prototype utilizing 0.5 micron CMOS technology. Low voltage analog to digital converters including the design of a 1.5V 8-bit 20MS/s pipeline converter is then presented. Techniques to improve the intrinsic matching of resistor-string digital to analog converters is described and demonstrated in the design of a high resolution control converter for 3G UMTS transceivers.
