Demand for wireless local area network systems has led to new frequency bands and new standards to accommodate higher data rates. Moreover, opportunities are increasing for the development of low- cost integrated WLAN systems. This guide for RF and high-speed analog circuit designers and students as well as wireless engineers studies the phase-locked loop as a basic building block of frequency synthesizers and WLAN receivers. It provides guidelines and engineering solutions for the design of loop filters in high- frequency PLLs. Rategh (Tavanza Inc.) and Lee (Stanford U.) discuss the different analog and digital frequency division techniques and introduce injection-locked frequency dividers as an alternative to conventional frequency dividers. c.

Introducing a new, pioneering approach to integrated circuit design Nanometer Frequency Synthesis Beyond Phase-Locked Loop introduces an innovative new way of looking at frequency that promises to open new frontiers in modern integrated circuit (IC) design. While most books on frequency synthesis deal with the phase-locked loop (PLL), this book focuses on the clock signal. It revisits the concept of frequency, solves longstanding problems in on-chip clock generation, and presents a new time-based information processing approach for future chip design. Beginning with the basics, the book explains how clock signal is used in electronic applications and outlines the shortcomings of conventional frequency synthesis techniques for dealing with clock generation problems. It introduces the breakthrough concept of Time-Average-Frequency, presents the Flying-Adder circuit architecture for the implementation of this approach, and reveals a new circuit device, the Digital-to-Frequency Converter (DFC). Lastly, it builds upon these three key components to explain the use of time rather than level to represent information in signal processing. Provocative, inspiring, and chock-full of ideas for future innovations, the book features: A new way of thinking about the fundamental concept of clock frequency A new circuit architecture for frequency synthesis: the Flying-Adder direct period synthesis A new electronic component: the Digital-to-Frequency Converter A new information processing approach: time-based vs. level-based Examples demonstrating the power of this technology to build better, cheaper, and faster systems Written with the intent of showing readers how to think outside the box, Nanometer Frequency Synthesis Beyond the Phase-Locked Loop is a must-have resource for IC design engineers and researchers as well as anyone who would like to be at the forefront of modern circuit design.

The latest frequency synthesis techniques, including sigma-delta,Diophantine, and all-digital Sigma-delta is a frequency synthesis technique that has risen inpopularity over the past decade due to its intensely digital natureand its ability to promote miniaturization. A continuation of thepopular Frequency Synthesis by Phase Lock, Second Edition, thistimely resource provides a broad introduction to sigma-delta bypairing practical simulation results with cutting-edge research.Advanced Frequency Synthesis by Phase Lock discusses bothsigma-delta and fractional-n—the still-in-use forerunner tosigma-delta—employing Simulink® models and detailedsimulations of results to promote a deeper understanding. After a brief introduction, the book shows how spurs areproduced at the synthesizer output by the basic process anddifferent methods for overcoming them. It investigates how variousdefects in sigma-delta synthesis contribute to spurs or noise inthe synthesized signal. Synthesizer configurations are analyzed,and it is revealed how to trade off the various noise sources bychoosing loop parameters. Other sigma-delta synthesis architecturesare then reviewed. The Simulink simulation models that provided data for thepreceding discussions are described, providing guidance in makinguse of such models for further exploration. Next, another methodfor achieving wide loop bandwidth simultaneously with fineresolution—the Diophantine Frequency Synthesizer—isintroduced. Operation at extreme bandwidths is also covered,further describing the analysis of synthesizers that push theirbandwidths close to the sampling-frequency limit. Lastly, the bookreviews a newly important technology that is poised to becomewidely used in high-production consumerelectronics—all-digital frequency synthesis. Detailed appendices provide in-depth discussion on variousstages of development, and many related resources are available fordownload, including Simulink models, MATLAB® scripts,spreadsheets, and executable programs. All these features make thisauthoritative reference ideal for electrical engineers who want toachieve an understanding of sigma-delta frequency synthesis and anawareness of the latest developments in the field.

This book describes the design and implementation of an electronic subsystem called the frequency synthesizer, which is a very important building block for any wireless transceiver. The discussion includes several new techniques for the design of such a subsystem which include the usage modes of the wireless device, including its support for several leading-edge wireless standards. This new perspective for designing such a demanding subsystem is based on the fact that optimizing the performance of a complete system is not always achieved by optimizing the performance of its building blocks separately. This book provides “hands-on” examples of this sort of co-design of optimized subsystems, which can make the vision of an always-best-connected scenario a reality.

The increasingly demanding performance requirements of communications systems, as well as problems posed by the continued scaling of silicon technology, present numerous challenges for the design of frequency synthesizers in modern transceivers. This book contains everything you need to know for the efficient design of frequency synthesizers for today's communications applications. If you need to optimize performance and minimize design time, you will find this book invaluable. Using an intuitive yet rigorous approach, the authors describe simple analytical methods for the design of phase locked loop (PLL) frequency synthesizers using scaled silicon CMOS and bipolar technologies. The entire design process, from system-level specification to layout, is covered comprehensively. Practical design examples are included, and implementation issues are addressed. A key problem-solving resource for practitioners in IC design, the book will also be of interest to researchers and graduate students in electrical engineering.
