Integrated Rf Building Blocks for Wireless Communication Transceivers

The wireless communication systems have become an important part of our lives. The ever increasing demand toward lower cost makes the task of the wireless communication circuit designer more and more challenging. This demand translates into the specifications as the need of designing the circuits with lower power consumption, with smaller die area but without any compromise from the final goal of higher performance. The circuit design for wireless transceiver front-ends has an additional complexity due to the high frequency of operation involved. This book includes discussions on the fully-integrated VCOs, prescalers and Q-enhanced LC bandpass filters on silicon within the framework of RF integrated circuit design for wireless communication transceivers. The advantages and shortcomings of the circuits are presented together with the associated design trade-offs, based on simplified noise and nonlinearity analyses. Measurement results of the designed and implemented LC VCOs, a dual-modulus prescaler and a Q-enhanced LC bandpass filter are provided. This book will be of interest to analog circuit designers and researchers in the field of RF IC design.
