This book presents a state of the art review of integrated circuits, systems and transceivers for wireless and mobile communications. Contributions from world-class researchers focus upon the most recent developments in key RF, IF and baseband components and subsystems and transceiver architecture in CMOS technology. Adopting a top-down approach from wireless communications systems, mobile terminals and transceivers, to constituent components, this book covers the whole range of baseband, IF and RF issues in a systematic way. Circuit and system techniques for design and implementation of reconfigurable low voltage and low power single-chip CMOS transceivers for both mobile cellular and wireless LAN applications are included.
