Phaselock Techniques
A greatly revised and expanded account of phaselock technology The Third Edition of this landmark book presents new developments in the field of phaselock loops, some of which have never been published until now. Established concepts are reviewed critically and recommendations are offered for improved formulations. The work reflects the author's own research and many years of hands-on experience with phaselock loops. Reflecting the myriad of phaselock loops that are now found in electronic devices such as televisions, computers, radios, and cell phones, the book offers readers much new material, including: Revised and expanded coverage of transfer functions Two chapters on phase noise Two chapters examining digital phaselock loops A chapter on charge-pump phaselock loops Expanded discussion of phase detectors and of oscillators A chapter on anomalous phaselocking A chapter on graphical aids, including Bode plots, root locus plots, and Nichols charts As in the previous editions, the focus of the book is on underlying principles, which remain valid despite technological advances. Extensive references guide readers to additional information to help them explore particular topics in greater depth. Phaselock Techniques, Third Edition is intended for practicing engineers, researchers, and graduate students. This critically acclaimed book has been thoroughly updated with new information and expanded for greater depth.
Why Read This Book
You will get an authoritative, hands-on treatment of phase-locked loop (PLL) theory and design that blends rigorous analysis with practical rules of thumb drawn from decades of real engineering experience. The third edition adds deep, up-to-date coverage of phase noise, charge-pump and digital PLL architectures, so you can analyze, simulate, and optimize PLLs for communications, radar, and timing applications.
Who Will Benefit
Practicing RF/communications engineers, DSP and systems designers, and graduate students who must design or analyze PLLs for frequency synthesis, clock recovery, or receiver synchronization.
Level: Advanced — Prerequisites: Undergraduate-level signals and systems, basic circuit analysis (analog/digital), control theory/feedback fundamentals, and comfort with complex algebra; familiarity with MATLAB or SPICE is recommended.
