CMOS Radio Transceiver IC Design

The radio transceiver is essential to wireless communications. It provides the necessary link between two untethered devices and integrates a wide array of circuits, including RF amplifiers, mixers, frequency synthesizers, filters, and data converters.

CMOS technology provides for low-cost microelectronics. Its widespread use for digital modems makes it the obvious choice for the radio transceiver. Understanding the key circuits comprising the radio transceiver is invaluable to the design process.

This intense course presents an overview of CMOS technology, reviews RF concepts, and explores the critical circuits that form the radio transceiver. Instruction provides the essential mathematical equations, performance curves, and important trade-offs related to the design of these circuits. Design examples are provided throughout the course.

Course Materials

The text, The Design of CMOS Radio-Frequency Integrated Circuits, Second Edition, Thomas H. Lee (Cambridge University Press, 2004) and lecture notes are distributed on the first day of the course. The notes are for participants only and are not for sale.

Coordinator and Lecturer

John B. Groe, MS, Principal Consultant, Innovate Radio, San Diego, California. Mr. Groe has been investigating and developing advanced radio architectures and circuit concepts for over 25 years. During this time, he has designed several radio transceivers for a wide range of applications, including a multimode direct conversion receiver and wideband polar transmitter. He also has extensive experience with fractional-N phase-locked loops and ΔΣ-modulated data converters.

Mr. Groe’s research combines in-depth system and circuit knowledge developed at leading wireless communications companies, including Nokia and TRW. During his time at Nokia, he directed focused research activities at UCLA, UCSD, and UCB. His research has led to 45 patents and several other applications—all in the field of wireless communications.

Mr. Groe is the author of a number of journal papers, is a peer reviewer, and is recognized as a Senior Member of IEEE. He is coauthor of CDMA Mobile Radio Design and a contributor to Circuits and Systems for Future Generations of Wireless Communications. He is a part-time professor at UCSD and a guest lecturer at UCLA.
