Ultra-wideband technology (UWB) has received tremendous attention since the FCC license release in 2002, which expedited the research and development of UWB technologies on consumer products. The applications of UWB range from ground penetrating radar, distance sensor, through wall radar to high speed, short distance communications. The CMOS integrated circuit is an attractive, low cost approach for implementing UWB technology. The improving cut-off frequency of the transistor in CMOS process makes the CMOS circuit capable of handling signal at multi-giga herz. However, some design challenges still remain to be solved. Unlike regular narrow band signal, the UWB signal is discrete pulse instead of continuous wave (CW), which results in the occupancy of wide frequency range. This demands that UWB front-end circuits deliver both time domain and frequency domain signal processing over broad bandwidth. Witnessing these technique challenges, this dissertation aims at designing novel, high performance components for UWB signal generation, down-conversion, as well as accurate timing control using low cost CMOS technology. We proposed, designed and fabricated a carrier based UWB transmitter to facilitate the discrete feature of the UWB signal. The transmitter employs novel twostage -switching to generate carrier based UWB signal. The structure not only minimizes the current consumption but also eliminates the use of a UWB power amplifier. The fabricated transmitter is capable of delivering tunable UWB signal over the complete 3.1GHz -10.6GHz UWB band. By applying the similar two-stage switching approach, we were able to implement a novel switched-LNA based UWB sampling receiver frontend. The proposed front-end has significantly lower power consumption compared to previously published design while keep relatively high gain and low noise at the same time. The designed sampling mixer shows unprecedented performance of 9-12dB voltage conversion gain, 16-25dB noise figure, and power consumption of only 21.6mW(with buffer) and 11.7mW(without buffer) across dc to 3.5GHz with 100M-Hz sampling frequency. The implementation of a precise delay generator is also presented in the dissertation. It relies on an external reference clock to provide accurate timing against process, supply voltage and temperature variation through a negative feedback loop. The delay generator prototype has been verified having digital programmability and tunable delay step resolution. The relative delay shift from desired value is limited to within 0.2%.

Download and read online ebook Design of CMOS RFIC Ultra-Wideband Impulse Transmitters and Receivers write by Cam Nguyen. This book was released on 2017-03-21. Design of CMOS RFIC Ultra-Wideband Impulse Transmitters and Receivers available in PDF, EPUB and Kindle. 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.

Download and read online ebook Design of Ultra-Low Power Impulse Radios write by Alyssa Apsel. This book was released on 2013-10-29. Design of Ultra-Low Power Impulse Radios available in PDF, EPUB and Kindle. This book covers the fundamental principles behind the design of ultra-low power radios and how they can form networks to facilitate a variety of applications within healthcare and environmental monitoring, since they may operate for years off a small battery or even harvest energy from the environment. These radios are distinct from conventional radios in that they must operate with very constrained resources and low overhead. This book provides a thorough discussion of the challenges associated with designing radios with such constrained resources, as well as fundamental design concepts and practical approaches to implementing working designs. Coverage includes integrated circuit design, timing and control considerations, fundamental theory behind low power and time domain operation, and network/communication protocol considerations.
