Preface

This book is concerned with integrated circuits and systems for wireless and mobile communications. Circuit techniques and implementation of reconfigurable low-voltage and low-power single-chip CMOS transceivers for multiband and multimode universal wireless communications are the focus of the book. Applications encompass both long-range mobile cellular communications (GSM and UMTS) and short-range wireless LANs (IEEE802.11 and Bluetooth). Recent advances in research into transceiver architecture, RF frontend, analogue baseband, RF CAD and automatic testing are reported. The book, containing ten chapters, covers topics including receiver architectures, reconfigurable and programmable analogue base-band arrays, design and on-chip tuning of active IC filters including polyphase filters, receiver front-end modules (LNA, VCO, mixer) and chips, transmit power amplifiers, parasitic-aware RF design and optimisation, and on-chip testing of communication ICs. The book can be used as a text or reference book for a broad range of readers from both academia and industry.

I would like to thank Robin Mellors-Bourne, Director of the Publishing Department of the IEE for his support and encouragement. My gratitude also goes to David Haigh of UCL, IEE Circuits, Devices and Systems Series Editor, for his help, in particular with Chapter 1. Assistance from the editorial and production team at IEE is acknowledged. I am very grateful to the authors of the chapters for their great effort and high speed in contributing such high-quality chapters. Their professionalism is greatly appreciated. I should also thank my lovely family, Xiaohui, Bo and Lucy for their understanding and support.

During the preparation of this book, I was also Guest Editor of a special issue on ‘RF circuits and systems for wireless communications’ for IEE Proceedings: Circuits, Devices and Systems (published in December 2002). Some of the book chapter contributors have written papers for that special issue. I am pleased to see that some of the book chapters have benefited from the special issue.
