This guide's authors are the industry's leading experts in signal integrity and PDN. Smith has over 30 years' experience in electronics, system and PDN design at IBM, Sun Microsystems and Altera Corporation, and has architected today's most popular systematic approach to PDN design. Bogatin also has more than 30 years' experience in signal integrity, and has written the field's most popular SI text book, Signal and Power Integrity-Simplified. Here, they thoroughly illuminate the core principles at the foundation of PDN performance, including impedance, resonance, inductance, and signal propagation. They offer practical insights for understanding noise sources, and show how design features affect noise. Next, they help readers strengthen their intuition about how physical design decisions affect electrical performance, and complement their intuition with detailed analysis to carefully balance cost and robustness. Readers will find valuable rules of thumb, analytical approximations, examples of numerical simulations, and practical coverage of all PDN elements, from chip features to package, board, and voltage regulator module (VRM). The authors show to use measurement to anchor your designs to reality, characterizing components in the frequency domain, and characterizing systems in the time domain. They review the principles behind each measurement technique, as present multiple examples of measured performance of real world components and systems.
