This book was released on 2010-08-05 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are continuous efforts focussed on improving road traffic safety worldwide. Numerous vehicle safety features have been invented and standardized over the past decades. Particularly interesting are the driver assistance systems, since these can considerably reduce the number of accidents by supporting drivers’ perception of their surroundings. Many driver assistance features rely on radar-based sensors. Nowadays the commercially available automotive front-end sensors are comprised of discrete components, thus making the radar modules highly-priced and suitable for integration only in premium class vehicles. Realization of low-cost radar fro- end circuits would enable their implementation in inexpensive economy cars, c- siderably contributing to traffic safety. Cost reduction requires high-level integration of the microwave front-end c- cuitry, specifically analog and digital circuit blocks co-located on a single chip. - cent developments of silicon-based technologies, e.g. CMOS and SiGe:C bipolar, make them suitable for realization of microwave sensors. Additionally, these te- nologies offer the necessary integration capability. However, the required output power and temperature stability, necessary for automotive radar sensor products, have not yet been achieved in standard digital CMOS technologies. On the other hand, SiGe bipolar technology offers excellent high-frequency characteristics and necessary output power for automotive applications, but has lower potential for - alization of digital blocks than CMOS.

Download or read book Low Power UWB CMOS Radar Sensors written by Hervé Paulino and published by Springer Science & Business Media. This book was released on 2008-04-30 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Power UWB CMOS Radar Sensors deals with the problem of designing low cost CMOS radar sensors. The radar sensor uses UWB signals in order to obtain a reasonable target separation capability, while maintaining a maximum signal frequency below 2 GHz. This maximum frequency value is well within the reach of current CMOS technologies. The use of UWB signals means that most of the methodologies used in the design of circuits and systems that process narrow band signals, can no longer be applied. Low Power UWB CMOS Radar Sensors provides an analysis between the interaction of UWB signals, the antennas and the processing circuits. This analysis leads to some interesting conclusions on the types of antennas and types of circuits that should be used. A methodology to compare the noise performance of UWB processing circuits is also derived. This methodology is used to analyze and design the constituting circuits of the radar transceiver. In order to validate the design methodology a CMOS prototype is designed and experimentally evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: CMOS Cellular Receiver Front-Ends: From Specification to Realization deals with the design of the receive path of a highly-integrated CMOS cellular transceiver for the GSM-1800 cellular system. The complete design trajectory is covered, starting from the documents describing the standard down to the systematic development of CMOS receiver ICs that comply to the standard. The design of CMOS receivers is tackled at all abstraction levels: from architecture level, via circuit level, down to the device level, and the other way around. Different receiver architectures are compared with respect to integratability, achievable performance and required building block specifications. The requirements of the GSM-1800 standard are mapped onto a set of measurable specifications for a highly-integrated low-IF receiver and distributed among the different building blocks. Several circuit topologies are presented that realize the main functions of the receive path. The dynamics of the elementary specifications of these circuits are explained in terms of the operating point of the involved devices. Wherever possible, this is done using analytical expressions. Based on these insights, detailed sizing procedures are developed to systematically size these RF circuits for a set of specifications. The feasibility of meeting the requirements of today's high-end cellular standards is demonstrated in a mainstream submicron CMOS technology by the development of two highly-integrated GSM-1800 receivers. The theoretical core of the book discusses the fundamental and more advanced aspects of RF CMOS design. It focuses specifically on all aspects of the design of high-performance CMOS low-noise amplifiers. Attempts are made to reconcile the analog designer's and the RF designer's point of view on how to look at submicron CMOS transistors. Special attention is given to the fallacies and pitfalls of input matching in a CMOS context. A methodology for the systematic design of CMOS low-noise amplifiers is presented which is based on a bank of analytical equations for all important LNA specifications. The method is validated by the design of a low power, extremely low noise CMOS GPS LNA.

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.

This book was released on 2007-05-08 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the exponential growth of the number of Internet nodes, the volume of the data transported on the backbone has increased with the same trend. The load of the global Internet backbone will soon increase to tens of terabits per second. This indicates that the backbone bandwidth requirements will increase by a factor of 50 to 100 every seven years. Transportation of such high volumes of data requires suitable media with low loss and high bandwidth. Among the available transmission media, optical fibers achieve the best performance in terms of loss and bandwidth. High-speed data can be transported over hundreds of kilometers of single-mode fiber without significant loss in signal integrity. These fibers progressively benefit from reduction of cost and improvement of perf- mance. Meanwhile, the electronic interfaces used in an optical network are not capable of exploiting the ultimate bandwidth of the fiber, limiting the throughput of the network. Different solutions at both the system and the circuit levels have been proposed to increase the data rate of the backbone. System-level solutions are based on the utilization of wave-division multiplexing (WDM), using different colors of light to transmit s- eral sequences simultaneously. In parallel with that, a great deal of effort has been put into increasing the operating rate of the electronic transceivers using highly-developed fabrication processes and novel c- cuit techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Technology developments have made CMOS a strong candidate in high-frequency applications because of its low power, low cost and higher-level integration. However, as an essential element in an RF building block, a CMOS device is not as good as a BJT device in terms of speed and a HEMT device in terms of noise performance. Therefore, conventional low-frequency design techniques for CMOS circuits may not satisfy the requirements for high-frequency applications wherein the operating frequencies get close to the cut-off frequency of a CMOS device. This research work explores design techniques for various high-frequency circuits at 10 GHz, 60 GHz and up to 110 GHz. Individual building blocks including low-noise amplifiers, voltage-controlled oscillators, high-frequency true-single-phase-clock frequency dividers, and mm-wave amplifiers are studied thoroughly using both theoretical analysis and practical circuit designs. Related fundamental techniques, such as MOS device modeling and de-embedding techniques, are also explored. Furthermore, as a prototype of system-level integration, a Ku-band LNB front-end is implemented for the application of a satellite receiver.

Download or read book CMOS Integrated Circuit Design for Ultra wideband Transmitters and Receivers written by Rui Xu and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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%.
