Phase-Locked Loops for Wireless Communications

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.
