Digital Subsampling Phase Lock Techniques for Frequency Synthesis and Polar Transmission


Book Description

This book explains concepts behind fractional subsampling-based frequency synthesis that is re-shaping today’s art in the field of low-noise LO generation. It covers advanced material, giving clear guidance for development of background-calibrated environments capable of spur-free synthesis and wideband phase modulation. It further expands the concepts into the field of subsampling polar transmission, where the newly developed architecture enables unprecedented spectral efficiency levels, unquestionably required by the upcoming generation of wireless standards.




Advanced Phase-lock Techniques


Book Description

A unified approach to phase-lock tecnology, spanning large to small signal-to-noise ratio applications




Frequency Acquisition Techniques for Phase Locked Loops


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.

Phaselock Tecniques,second Edition


Book Description

This second edition of Phaselock Techniques is -- as was the first -- the standard reference on the subject. Greatly expanded and largely rewritten to reflect a better understanding of the subject, the book presents much new material, some published here for the first time. Explanation of fundamentals is improved and expanded, and description of applications is greatly increased. The first portion of the book is a well-organized review of the fundamentals of phaselock, as well as a discussion of the underlying problems faced by designers. Most of this mateiral has been rewritten from the first edition. The material that follows deals with practical aspects of component circuits and with rational procedures for deciding upon phaselock loop parameters. The remaining chapters provide engineering descriptions and analyses of applications of phaselock. Most of this material is unique.Included are discussions of phaselocked modulators and demodulators, sythesizers, receivers, transponders, oscillator stabilizers, and data synchronizers.




Phase-Locked Loops for Wireless Communications


Book Description

Phase-Locked Loops for Wireless Communications: Digitial, Analog and Optical Implementations, Second Edition presents a complete tutorial of phase-locked loops from analog implementations to digital and optical designs. The text establishes a thorough foundation of continuous-time analysis techniques and maintains a consistent notation as discrete-time and non-uniform sampling are presented. New to this edition is a complete treatment of charge pumps and the complementary sequential phase detector. Another important change is the increased use of MATLAB®, implemented to provide more familiar graphics and reader-derived phase-locked loop simulation. Frequency synthesizers and digital divider analysis/techniques have been added to this second edition. Perhaps most distinctive is the chapter on optical phase-locked loops that begins with sections discussing components such as lasers and photodetectors and finishing with homodyne and heterodyne loops. Starting with a historical overview, presenting analog, digital, and optical PLLs, discussing phase noise analysis, and including circuits/algorithms for data synchronization, this volume contains new techniques being used in this field. Highlights of the Second Edition: Development of phase-locked loops from analog to digital and optical, with consistent notation throughout; Expanded coverage of the loop filters used to design second and third order PLLs; Design examples on delay-locked loops used to synchronize circuits on CPUs and ASICS; New material on digital dividers that dominate a frequency synthesizer's noise floor. Techniques to analytically estimate the phase noise of a divider; Presentation of optical phase-locked loops with primers on the optical components and fundamentals of optical mixing; Section on automatic frequency control to provide frequency-locking of the lasers instead of phase-locking; Presentation of charge pumps, counters, and delay-locked loops. The Second Edition includes the essential topics needed by wireless, optics, and the traditional phase-locked loop specialists to design circuits and software algorithms. All of the material has been updated throughout the book.

Theory of the Non-linear Analog Phase Locked Loop


Book Description

This book develops for the first time a complete and connected nonlinear theory for the analog Phase-Locked Loop (PLL) which clarifies the obscure points of its complex non-linear behaviour. The book suggests new non-linear models for the PLL components and applies the averaging method to analyse PLL. The book presents the physical interpretation of the PLL operation, locates the difficulties presented by its operation and suggests solutions to overcome these problems. Finally it provides closed form expressions for all the important measures of the PLL and proposes new design criteria.
