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
CMOS technology has now reached a state of evolution, in terms of both frequency and noise, where it is becoming a serious contender for radio frequency (RF) applications in the GHz range. Cutoff frequencies of about 50 GHz have been reported for 0.18 æm CMOS technology, and are expected to reach about 100 GHz when the feature size shrinks to 100 nm within a few years. This translates into CMOS circuit operating frequencies well into the GHz range, which covers the frequency range of many of today's popular wireless products, such as cell phones, GPS (Global Positioning System) and Bluetooth. Of course, the great interest in RF CMOS comes from the obvious advantages of CMOS technology in terms of production cost, high-level integration, and the ability to combine digital, analog and RF circuits on the same chip. This book discusses many of the challenges facing the CMOS RF circuit designer in terms of device modeling and characterization, which are crucial issues in circuit simulation and design.

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
While mobile phones enjoy the largest production volume ever of any consumer electronics products, the demands they place on radio-frequency (RF) transceivers are particularly aggressive, especially on integration with digital processors, low area, low power consumption, while being robust against process-voltage-temperature variations. Since mobile terminals inherently operate on batteries, their power budget is severely constrained. To keep up with the ever increasing data-rate, an ever-decreasing power per bit is required to maintain the battery lifetime. The RF oscillator is the second most power-hungry block of a wireless radio (after power amplifiers). Consequently, any power reduction in an RF oscillator will greatly benefit the overall power efficiency of the cellular transceiver. Moreover, the RF oscillators' purity limits the transceiver performance. The oscillator's phase noise results in power leakage into adjacent channels in a transmit mode and reciprocal mixing in a receive mode. On the other hand, the multi-standard and multi-band transceivers that are now trending demand wide tuning range oscillators. However, broadening the oscillator’s tuning range is usually at the expense of die area (cost) or phase noise. The main goal of this book is to bring forth the exciting and innovative RF oscillator structures that demonstrate better phase noise performance, lower cost, and higher power efficiency than currently achievable. Technical topics discussed in RF CMOS Oscillators for Modern Wireless Applications include:  Design and analysis of low phase-noise class-F oscillators Analyze a technique to reduce 1/f noise up-conversion in the oscillators Design and analysis of low power/low voltage oscillators Wide tuning range oscillators Reliability study of RF oscillators in nanoscale CMOS
