| Book Description | This book presents the design of ultra-wideband (UWB) impulse-based transmitter and receiver frontends, operating within the 3.1-10.6 GHz frequency band, using CMOS radio-frequency integrated-circuits (RFICs). CMOS RFICs are small, cheap, low power devices, better suited for direct integration with digital ICs as compared to those using III-V compound semiconductor devices. CMOS RFICs are thus very attractive for RF systems and, in fact, the principal choice for commercial wireless markets.
The book comprises seven chapters. The first chapter gives an introduction to UWB technology and outlines its suitability for high resolution sensing and high-rate, short-range ad-hoc networking and communications. The second chapter provides the basics of CMOS RFICs needed for the design of the UWB RFIC transmitter and receiver presented in this book. It includes the design fundamentals, lumped and distributed elements for RFIC, layout, post-layout simulation, and measurement. The third chapter discusses the basics of UWB systems including UWB advantages and applications, signals, basic modulations, transmitter and receiver frontends, and antennas. The fourth chapter addresses the design of UWB transmitters including an overview of basic components, design of pulse generator, BPSK modulator design, and design of a UWB tunable transmitter. Chapter 5 presents the design of UWB receivers including the design of UWB low-noise amplifiers, correlators, and a UWB 1 receiver. Chapter 6
covers the design of a UWB uniplanar antenna. Finally, a summary and conclusion is given in Chapter 7. |
| About the Author | Dr. Cam Nguyen joined the Department of Electrical and Computer Engineering of Texas A&M University in Dec. 1990, after working for more than twelve years in industry, where he now holds the position of Texas Instruments Endowed Professor.
He was with the National Science Foundation during 2003-2004 as Program Director of the Electronics, Photonics, and Device Technology Program and the Integrative Systems Program, responsible for research programs in RF electronics and wireless technologies. He was a Microwave Engineer with ITT Gilfillan Co., a Member of Technical Staff with Hughes Aircraft Co. (now Raytheon), and a Technical Specialist with Aeroject ElectroSystems Co. - all in California - a Member of Professional Staff with Martin Marietta Co. (now Lockheed-Martin) in Florida, and a Senior Staff Engineer and Program Manager at TRW (now Northrop Grumman) in California. While in industry, he led numerous RF, microwave and millimeter-wave activities. He also developed many RF, microwave and millimeter-wave integrated circuits and systems up to 220 GHz for communications, radar, and remote sensing.
He has published more than 240 papers, written 4 books and five book chapters, edited three books, and given more than 150 conference presentations and numerous invited presentations. Dr. Nguyen is the Founding Editor-in-Chief of Sensing and Imaging: An International Journal. He was also the Founding Chairman of the International Conference on Subsurface and Surface Sensing and Imaging Technologies and Applications. |
