Signal and Power Integrity - Simplified

This book brings together up-to-the-minute techniques for finding, fixing, and avoiding signal integrity problems in your design. Drawing on his work teaching several thousand engineers and graduate students, world-renowned expert Eric Bogatin systematically presents the root causes of all six families of signal integrity, power integrity, and electromagnetic compatibility problems. Bogatin reviews essential principles needed to understand these problems, and shows how to use best design practices and techniques to prevent or address them early in the design cycle. To help test and reinforce your understanding, this new edition adds questions and problems throughout. Bogatin also presents more examples using free tools, plus new content on high-speed serial links, reflecting input from 130+ of his graduate students.

For professionals and students at all levels of experience, this book emphasizes intuitive understanding, practical tools, and engineering discipline, rather than theoretical derivation or mathematical rigor. It has earned a well-deserved reputation as the #1 resource for getting signal integrity designs right-first time, every time.
