This book is written for academic and professional researchers designing communication systems for pervasive and low power applications. There is an introduction to wireless sensor networks, but the main emphasis of the book is on design techniques for low power, highly integrated transceivers. Instead of presenting a single design perspective, this book presents the design philosophies from three diverse research groups, providing three completely different strategies for achieving similar goals. By presenting diverse perspectives, this book prepares the reader for the countless design decisions they will be making in their own designs.This block diagram consists of a passive matching network, an isolation amplifier, an amplifier with time-varying gain, and ... The isolation amplifier between the antenna and the oscillator performs the following functions: it reduces RF leakage ... The time-varying nature of the loop gain is designed such that the oscillator transconductance periodically exceeds the critical gm necessary to induce instability.
