Radio Frequency Integrated Circuits and Systems

Описание

Preface
In the past twenty years, radio frequency (RF) integrated circuits in CMOS have
evolved dramatically, and matured. Started as a pure research topic in mid-1990 at
several universities, they have made their way into complex systems-on-a-chip
(SoCs) for wireless connectivity and mobile applications. The reason for this
dramatic evolution comes primarily from two main factors: the rapid improvement
of CMOS technology, and innovative circuits and architectures. In contrary to the
common belief that RF and analog circuits do not improve much with technology, a
faster CMOS process has enabled a number of topologies that have led to
substantially lower cost and power consumption. In fact, many of the recent
inventions may not have been possible if it were not for a better and faster
technology. This rapid change has caused the modern RF design to be somewhat
industry-based and, consequently, it is timely, and perhaps necessary, to provide an
industry perspective. To that extent, the main goal of this book has been to cover
possibly fewer topics, but in a much deeper fashion. Even for RF engineers
working on routine products in industry, a deep understanding of fundamental
concepts of RF IC design is very critical, and it is the intention of this work to
break this gap. During the course of writing the book, I have tried to address the
topics that I would have wanted as a wish list for my fellow future colleagues. Our
main focus then has been to elaborate the basic definitions and fundamental
concepts, while an interested designer with strong background can explore other
variations on his or her own.
The contents of this book stem largely from the RF courses taught at the
University of California Los Angeles and Irvine, as well as many years of product
experience at Broadcom. Accordingly, the book is intended to be useful both as a
text for students and as a reference book for practicing RF circuit and system
engineers. Each chapter includes several worked examples that illustrate the
practical applications of the material discussed, with examples of real life
products, and a problem set at the end (with solutions manual) to complement that.
