This book was released on 2010-06 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultra-wideband (UWB) impulse-radio technology has unique features including high data-rate as well as low power consumption with ranging and localization capabilities. An UWB front-end, however, has to accommodate design challenges resulting from the exceptional wide bandwidth of several GHz. This book discusses the implementation issues of the UWB impulse-radio transceiver front-end, including the performance analysis of practical systems and the design of radio-frequency integrated circuits for transceiver front-ends. A general framework for performance evaluation of practical impulse radio system is proposed and demonstrated in scenarios of high-speed data communications as well as low-data-rate wireless body-area networks. An inductorless low- noise amplifier is designed with syncretic adoption of thermal noise canceling, capacitor peaking, and current reuse. The CMOS ransmit/receive switch design with highest reported bandwidth and power handling capability are discussed with customized transistor layout and triple-well resistive body- floating techniques. The prototypes have been demonstrated in state-of-the-art 130nm CMOS technology.

This book was released on 2017-03-21 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the design and analysis of Ultra Wideband receivers for Multiband Orthogonal Frequency Division Multiplexing systems. A comprehensive analysis of distortion effects in UWB receivers for different interference scenarios is performed. Analytical expressions for the power spectral density of all relevant distortion products (cross-modulation, intermodulation and harmonic distortion) are derived for the first time. Calculations are presented to show the effect of these distortion effects on overall system performance. Expressions developed will help circuit and system designers to come to an optimum power consumption versus performance trade-off. An RF receiver front-end for MB-OFDM based UWB systems is designed. The receiver is the first to be designed without using any on-chip inductors or off-chip matching components. The receiver occupies only 0.35 mm sq. in a 0.18uM CMOS process, consists of a low-noise amplifier, downconverter and a bandpass filter. The measured receiver gain is 21 dB, Noise Figure is less than 6 dB, input IIP3 is -5 dBm and the receiver consumes 19.5 mA from a 2.3V supply. The receiver covers all the MB-OFDM bands from 3.1 GHz to 8 GHz.

This book was released on 2008 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently the techniques based on Impulse Radio (IR) Ultra Wideband (UWB) have experienced a growing interest in the field of wireless systems. An efficient technique known as Transmitted Reference (TR) UWB, has gained in popularity for low and medium data rates applications such as sensor networks. This technique uses two pulses per symbol period, which are strongly correlated and separated by a well known delay (D). The reception system is composed of a wideband analog delay element and a correlator. The delay line allows making a copy of the received signal with a delay that corresponds exactly to D; the correlation is then made with these two pulses. Despite the apparent simplicity of this type of receiver, its implementation in a low power integrated circuit is not an easy task, especially the delay element which must be wideband for UWB applications. > To overcome this difficulty, a new detection method called Time Delayed Sampling and Correlation (TDSC) has been proposed recently, which will be explained in this document. It uses two analog waveform samplers activated at different times; here the delay D between pulses is applied to the control signals of the two samplers. The delay is generated in a digital way; it becomes programmable and can be used in a multi-user context (a different delay for each user for example). > This document describes the design and implementation of a CMOS prototype for a TDSC-UWB receiver based on TR-UWB detection scheme. The prototype made in CMOS 0.35mm technology, allows the validation of the new detection concept, i.e. TDSC. Thanks to this prototype, it was possible to measure a -3 dB bandwidth of around 1.1 GHz and a sampling frequency of more than 7 GHz. This allows the detection of impulse signals with an input bandwidth of 500 MHz (" 2 ns), which is the minimum bandwidth for the UWB technology.

Download or read book CMOS Wireless Transceiver Design written by Jan Crols and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world of wireless communications is changing very rapidly since a few years. The introduction of digital data communication in combination with digital signal process ing has created the foundation for the development of many new wireless applications. High-quality digital wireless networks for voice communication with global and local coverage, like the GSM and DECT system, are only faint and early examples of the wide variety of wireless applications that will become available in the remainder of this decade. The new evolutions in wireless communications set new requirements for the trans ceivers (transmitter-receivers). Higher operating frequencies, a lower power consump tion and a very high degree of integration, are new specifications which ask for design approaches quite different from the classical RF design techniques. The integrata bility and power consumption reduction of the digital part will further improve with the continued downscaling of technologies. This is however completely different for the analog transceiver front-end, the part which performs the interfacing between the antenna and the digital signal processing. The analog front-end's integratability and power consumption are closely related to the physical limitations of the transceiver topology and not so much to the scaling of the used technology. Chapter 2 gives a detailed study of the level of integration in current transceiver realization and analyzes their limitations. In chapter 3 of this book the complex signal technique for the analysis and synthesis of multi-path receiver and transmitter topologies is introduced.
