Book Description
The latest frequency synthesis techniques, including sigma-delta, Diophantine, and all-digital Sigma-delta is a frequency synthesis technique that has risen in popularity over the past decade due to its intensely digital nature and its ability to promote miniaturization. A continuation of the popular Frequency Synthesis by Phase Lock, Second Edition, this timely resource provides a broad introduction to sigma-delta by pairing practical simulation results with cutting-edge research. Advanced Frequency Synthesis by Phase Lock discusses both sigma-delta and fractional-n—the still-in-use forerunner to sigma-delta—employing Simulink® models and detailed simulations of results to promote a deeper understanding. After a brief introduction, the book shows how spurs are produced at the synthesizer output by the basic process and different methods for overcoming them. It investigates how various defects in sigma-delta synthesis contribute to spurs or noise in the synthesized signal. Synthesizer configurations are analyzed, and it is revealed how to trade off the various noise sources by choosing loop parameters. Other sigma-delta synthesis architectures are then reviewed. The Simulink simulation models that provided data for the preceding discussions are described, providing guidance in making use of such models for further exploration. Next, another method for achieving wide loop bandwidth simultaneously with fine resolution—the Diophantine Frequency Synthesizer—is introduced. Operation at extreme bandwidths is also covered, further describing the analysis of synthesizers that push their bandwidths close to the sampling-frequency limit. Lastly, the book reviews a newly important technology that is poised to become widely used in high-production consumer electronics—all-digital frequency synthesis. Detailed appendices provide in-depth discussion on various stages of development, and many related resources are available for download, including Simulink models, MATLAB® scripts, spreadsheets, and executable programs. All these features make this authoritative reference ideal for electrical engineers who want to achieve an understanding of sigma-delta frequency synthesis and an awareness of the latest developments in the field.

Book Description
A through discussion of frequency synthesizers, including design and effects on systems Working engineers who design, specify, use, or test frequency synthesizers need to develop an intimate understanding of how these devices operate and their effects on the systems in which they are embedded. Frequency Synthesis by Phase Lock, Second Edition, offers complete coverage that includes both normal control system design and effects that occur due to sampling when bandwidths are pushed. While the discussion emphasizes phase-locked synthesizers, direct and digital synthesizers are covered as well. In addition to the usual discussion of second-order loops, this book describes characteristics of an important class of third-order loops and state-space analysis of loops of arbitrary order. It uses Matlab scripts (available for downloading via ftp) to produce computer-aided analyses, including complex nonlinear simulations of loops in the acquisition process; and it includes a significant volume of material on phase noise, its effects in synthesizer loops, and its impact on systems employing synthesizers. An important reference of rare power and clarity, Frequency Synthesis by Phase Lock, Second Edition, features: * Three new chapters covering architectures, sampling effects, and computer-aided engineering (CAE) * Multicurve graphs of transient and modulation responses for second-and third-order loops * Graphs of phase noise from 28 oscillators and 19 frequency dividers; noise theory and curves for IC oscillators * Charge-pump phase-frequency detectors extensively covered * Fractional-N, including DSP for improved spectrums * Multiple loops, including offset references

Book Description
How to acquire the input frequency from an unlocked state A phase locked loop (PLL) by itself cannot become useful until it has acquired the applied signal's frequency. Often, a PLL will never reach frequency acquisition (capture) without explicit assistive circuits. Curiously, few books on PLLs treat the topic of frequency acquisition in any depth or detail. Frequency Acquisition Techniques for Phase Locked Loops offers a no-nonsense treatment that is equally useful for engineers, technicians, and managers. Since mathematical rigor for its own sake can degenerate into intellectual "rigor mortis," the author introduces readers to the basics and delivers useful information with clear language and minimal mathematics. With most of the approaches having been developed through years of experience, this completely practical guide explores methods for achieving the locked state in a variety of conditions as it examines: Performance limitations of phase/frequency detector–based phase locked loops The quadricorrelator method for both continuous and sampled modes Sawtooth ramp-and-sample phase detector and how its waveform contains frequency error information that can be extracted The benefits of a self-sweeping, self-extinguishing topology Sweep methods using quadrature mixer-based lock detection The use of digital implementations versus analog Frequency Acquisition Techniques for Phase Locked Loops is an important resource for RF/microwave engineers, in particular, circuit designers; practicing electronics engineers involved in frequency synthesis, phase locked loops, carrier or clock recovery loops, radio-frequency integrated circuit design, and aerospace electronics; and managers wanting to understand the technology of phase locked loops and frequency acquisition assistance techniques or jitter attenuating loops.

Book Description
With the advent of integrated circuits (IC), digital systems havebecome widely used in modern electronic devices, includingcommunications and measurement equipment. Direct Digital FrequencySynthesizers (DDS) are used in communications as transmitterexciters and local oscillators in receivers. The advantages aresuperior frequency stability, the same as that of the driving clockoscillator, and short switching times. The difficulties are loweroutput frequencies and rather large spurious signals. Compiled for practicing engineers who do not have theprerequisite of a specialist's knowledge in Direct DigitalFrequency Synthesizers (DDS), this collection of 40 importantreprinted papers and 9 never-before published contributionspresents a comprehensive introduction to DDS properties and a clearunderstanding of actual devices. The information in this volume canlead to easier computer simulations and improved designs. Featured topics include: * Discussion of principles and state of the art of wide-rangeDDS * Investigation of spurious signals in DDS * Combination of DDS with Phase Lock Loops (PLL) * Examination of phase and background 'noise' in DDS * Introduction to Digital to Analog Conversion (DAC) * Analysis of mathematics of quasiperiodic omission ofpulses DDFS can also serve as a textbook for students seeking essentialbackground theory.

Book Description
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.
