Wireless communication is witnessing tremendous growth with proliferationof different standards covering wide, local and personal area networks (WAN,LAN and PAN). The current trends call for designs that allow:Smooth migration to future generations of wireless standards with higher data rates for multimedia applications;Convergence of wireless services allowing access to different standards from the same wireless device;Cost effective design solutions for intercontinental roaming.This requires designs that work across multiple wireless standards, can easilybe reused, achieve maximum hardware share at minimum power consumptionlevels particularly for mobile battery-operated devices.While serious efforts are currently underway to develop highly integratedsolutions for digital basebands covering multiple standards, today’s emergingmulti-standard, multi-band wireless devices use "stacked" transceivers, i.e. separate transceivers for different standards. This represents a major bottleneck in attempting to achieve higher levels of integration and reduce the bill of material for a multi-standard wireless device. Development of radio architecturesand mixed-signal design solutions that support multiple standards is thereforeneeded. This is one of the main objectives of this book.This is the first book on the subject of multi-standard wireless receivers. Itcovers both the analysis and design aspects of CMOS radio receivers with primaryfocus on receivers for mobile terminals. The subject of multi-standard data converter design for base stations is also covered. The book is the first todetail a complete analysis of a multi-standard receiver chain from the antennato the data converter establishing the design specifications of all blocks in boththe radio and mixed-signal parts. The specifications are conveniently tabulatedthroughout the book and span a level of details from the noise figure and linearity requirements of RF blocks down to such circuit details as, e.g., DC gain,settling behavior, noise and matching requirements of amplifiers (OTAs) inthe data converter. The focus is on the third- generation backward-compatibleUMTS (WCDMA and GSM standards) as well as the short distance cordless DECT standard. However, the techniques and design methods presented inthe book can easily be adapted to other multi-standard application scenariosencompassing, for example, GPS, WLAN and Bluetooth.As such the book will serve as a reference for RF IC and mixed signaldesigners, wireless receiver system designers, design managers and projectleaders in industry, particularly those in the wireless semiconductor industry.The book could also serve as a reference or a text for a first year graduate course on the subject for electrical and /or computer engineering majors.One of the most critical challenges to overcome in the design of multistandardterminals for mobile and personal communication systems is to find the maximum number of commonalties amongst the different wireless standards of interest to allow the highest possible degree of integration, under the constraints of low voltage and low power consumption. The starting point in the design process of multi-standard terminals is to set up a common system architecture capable of implementing various standards and supporting higher levels of system integration of both the radio and the digital baseband parts.This involves a system partitioning strategy leading to a chip set, a system inpackage or ultimately a single system-on-chip solution. This also calls for radiodesign solutions with mixed signal strategies that take full advantage of CMOStechnology scale-down by moving functions, such as channel select filtering,offset compensation, modulation and demodulation, to the digital domain.
