A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed oscillator. They are found in modern devices like radio receivers, mobile phones, and GPS systems. This comprehensive resource offers RF and microwave engineers a thorough overview of both well-established and recently developed frequency synthesizer design techniques. Professionals find expert guidance on all design aspects, including main architectures, key building blocks, and practical circuit implementation. Engineers learn the development process and gain a solid understanding of how to build a synthesizer from a basic diagram to the final product. Starting with a simple single-loop PLL example, the book progressively examines various alternatives -- fractional-N, DDS, frequency offset, multiloop and more - to achieve required performance objectives. This unique volume gathers a collection of block diagrams, clever circuits, design recipes, and other hard-to-find information that is usually treated as "design secrets". Written in a simple yet rigorous style with numerous illustrations, the book is an all-in-one reference for both beginner and experienced designers.

Current literature is filled with textbooks and research papers describing frequency synthesizers from a front-end wireless transceiver perspective. The emphasis has historically been on evaluating the frequency synthesizer’s performance in the frequency domain, i.e. in terms of phase noise and spurious signals. As microprocessor frequency surges, the need to understand digital requirements for low-jitter and the design of low-jitter frequency synthesizers and clock generators becomes increasingly important. Clock Generators for SOC Processors is dedicated to the time-domain (i.e. jitter) design and analysis of frequency sythesizers and clock generators for microprocessor applications. In the past, such explanations have been scattered, and have not, to this date, been gathered into one comprehensive textbook. Clock Generators for SOC Processors also focuses on the CMOS IC implementation of such synthesizers. An entire chapter is dedicated to low-voltage mixed-signal integrated circuit design in deep submicron CMOS technologies. Subsequent chapters discuss the design and analysis of the most common frequency synthesizer, the phase-locked loop (PLL), as well as state-of-the-art innovative architectures suitable for system-on-a-chip (SOC) processors. Design for Testability (DFT) is also discussed in the context of frequency synthesizers in SOC processors. The book concludes by discussing some of the most common issues that arise in clock interfacing, clock distribution, and accurate delay generation through delay-locked loops (DLLs) as they apply to SOC processors. Such issues mainly arise from having to communicate data and clock signals across multiple clock and power domains. Clock Generators for SOC Processors provides numerous real world applications, as well as practical rules-of-thumb for modern designers to use at the system, architectural, and circuit level.
