Book Description
A new and innovative paradigm for RF frequency synthesis and wireless transmitter design Learn the techniques for designing and implementing an all-digital RF frequency synthesizer. In contrast to traditional RF techniques, this innovative book sets forth digitally intensive design techniques that lead the way to the development of low-cost, low-power, and highly integrated circuits for RF functions in deep submicron CMOS processes. Furthermore, the authors demonstrate how the architecture enables readers to integrate an RF front-end with the digital back-end onto a single silicon die using standard ASIC design flow. Taking a bottom-up approach that progressively builds skills and knowledge, the book begins with an introduction to basic concepts of frequency synthesis and then guides the reader through an all-digital RF frequency synthesizer design: Chapter 2 presents a digitally controlled oscillator (DCO), which is the foundation of a novel architecture, and introduces a time-domain model used for analysis and VHDL simulation Chapter 3 adds a hierarchical layer of arithmetic abstraction to the DCO that makes it easier to operate algorithmically Chapter 4 builds a phase correction mechanism around the DCO such that the system's frequency drift or wander performance matches that of the stable external frequency reference Chapter 5 presents an application of the all-digital RF synthesizer Chapter 6 describes the behavioral modeling and simulation methodology used in design The final chapter presents the implementation of a full transmitter and experimental results. The novel ideas presented here have been implemented and proven in two high-volume, commercial single-chip radios developed at Texas Instruments: Bluetooth and GSM. While the focus of the book is on RF frequency synthesizer design, the techniques can be applied to the design of other digitally assisted analog circuits as well. This book is a must-read for students and engineers who want to learn a new paradigm for RF frequency synthesis and wireless transmitter design using digitally intensive design techniques.

Book Description
A frequency synthesizer is one of the most critical building blocks in any wireless transceiver system. Its design is getting more and more challenging as the demand for low-voltage low-power high-frequency wireless systems continuously grows. As the supply voltage is decreased, many existing design techniques are no longer applicable. This book provides the reader with architectures and design techniques to enable CMOS frequency synthesizers to operate at low supply voltage at high frequency with good phase noise and low power consumption. In addition to updating the reader on many of these techniques in depth, this book will also introduce useful guidelines and step-by-step procedure on behaviour simulations of frequency synthesizers. Finally, three successfully demonstrated CMOS synthesizer prototypes with detailed design consideration and description will be elaborated to illustrate potential applications of the architectures and design techniques described. For engineers, managers and researchers working in radio-frequency integrated-circuit design for wireless applications.

Book Description
The recent boom in the mobile telecommunication market has trapped the interest of almost all electronic and communication companies worldwide. New applications arise every day, more and more countries are covered by digital cellular systems and the competition between the several providers has caused prices to drop rapidly. The creation of this essentially new market would not have been possible without the ap pearance of smalI, low-power, high-performant and certainly low-cost mobile termi nals. The evolution in microelectronics has played a dominant role in this by creating digital signal processing (DSP) chips with more and more computing power and com bining the discrete components of the RF front-end on a few ICs. This work is situated in this last area, i. e. the study of the full integration of the RF transceiver on a single die. Furthermore, in order to be compatible with the digital processing technology, a standard CMOS process without tuning, trimming or post-processing steps must be used. This should flatten the road towards the ultimate goal: the single chip mobile phone. The local oscillator (LO) frequency synthesizer poses some major problems for integration and is the subject of this work. The first, and also the largest, part of this text discusses the design of the Voltage Controlled Oscillator (VCO). The general phase noise theory of LC-oscillators is pre sented, and the concept of effective resistance and capacitance is introduced to char acterize and compare the performance of different LC-tanks.

Book Description
"Frequency synthesizers based on phase-locked loop (PLL) are ubiquitous components in RF communication systems. Frequency synthesizer PLLs must comply with the stringent requirements of RF systems such as noise, linearity, locking time, stability, and power consumption. The continuous shrinkage of the technology dimensions and power supply values exacerbated the situation and made the design more daunting especially at high frequencies. Integrability and long-life batteries have become extremely important targets in modern life. The ability to incorporate multiple standards in one device has recently stimulated a great deal of interest and brought to existence applications such as software-defined radio (SDR) and cognitive radio (CR). Such applications require very wide tuning range frequency synthesizers to cover multiple standards. The ability to cover this wide range with a single frequency synthesizer PLL is very desirable in terms of cost, area, and power. In this thesis, we tackle high frequency synthesis in light of the challenges imposed by modern CMOS technologies. More specifically, we tackle two design challenges. The first challenge is the need for wide tuning-range frequency synthesizer PLLs; and the second challenge is the need for analog circuits, including frequency synthesizer PLLs, that can operate from supply voltages below 0.6 V as predicted by semiconductor roadmaps for the next decade. In response to these technology demands, we provide three different IC implementations with measurement results to verify the theoretical findings. We demonstrate two frequency synthesizer PLLs in 65 nm CMOS technology. The first PLL focuses on wide tuning-range for applications such as SDR and CR, while operating from a supply voltage as low as 1.2 V. A continuous frequency range from 156.25 MHz to 10 GHz is achieved using a single frequency synthesizer PLL. The second PLL focuses on sub-1 V operation to generate a low-noise output. This PLL operates from a 0.55 V power supply and consumes 3 mW of power. The designed PLLs show comparable performance with the state-of-the-art PLLs in the literature in CMOS and other technologies. Furthermore, a third IC implementation of an ultra-low-voltage operational-transconductance-amplifier (OTA) is presented. The OTA combines different low-voltage techniques along with a novel biasing technique that allows operation from a supply voltage as low as 0.35 V. The ultra-low-voltage OTA can be used as a building block for the design of other biasing circuitry at low voltage such as bandgap references and voltage regulators." --

Book Description
Abstract: PLL (Phase-Locked Loop) frequency synthesizers are used in wireless transceivers for frequency conversion. Recent directions in PLL frequency synthesizer research and development are to fully integrate PLL synthesizers in CMOS technology, to improve phase noise performance, and to operate wide range of frequency bands and channel bandwidths. Fully integration of synthesizers in CMOS technology is desired for low cost, low power consumption and small size in mobile wireless terminals. Low phase noise is required by digital modulation techniques which have been used in new mobile standards for the efficient use of the frequency spectrum. Operation over a wide range of frequency bands and channel bandwidths are required to support migration and backward compatibility in the wireless standard evolution. This work investigates the PLL frequency synthesizer design and implementation in CMOS technology with focus on integration of wideband VCOs (Voltage-Controlled Oscillators). Phase noise of a PLL synthesizer is a major design parameter. A PLL noise model is developed for noise optimization purposes. Wideband RF VCO design with sub-bands is investigated. Frequency planning, synthesizer architecture and technology considerations are also explored for wideband VCO design. Band switching techniques VCO tuning range presented. Active VCO circuit topologies and resonator design are also presented. The PLL frequency synthesizers are designed and implemented for a multi-band/standard(IEEE 802.11a/b/g) WLAN radio in 0.18um CMOS. Phase noise trade-offs for PLL design are explored in this application. Development and design of a wideband VCO for this application is also presented. An auto calibration circuit is developed for VCO tuning band selection. Another application of the wideband PLL frequency synthesizer is designed and implemented for a fully integrated dual-mode frequency synthesizer for GSM and WCDMA standards in 0.5um CMOS. A hybrid integer-N/fractional-N architecture is developed to meet the multi-standard requirements. Design and implementation of high performance RF VCO depends on the RF models of the devices. RF CMOS characterization and modeling techniques are explored. Microwave wafer measurement and calibration techniques are also investigated for CMOS technology.
