This book assists engineers - both recent graduates and working product designers - in designing high-speed circuits. The authors apply circuit theory, circuit simulation tools, and practical experience to help the engineer understand semiconductor modeling as applied to high-speed digital designs. The emphasis is on semiconductor modeling, with PCB transmission line effects, equipment enclosure effects, and other modeling issues discussed as needed. The text addresses many practical considerations, including process variation, model accuracy, validation and verification, signal integrity, and design flow. Readers will benefit from its survey of modeling for semiconductors, packages, and interconnects, along with usable advice on how to get complex, high-speed prototypes to work on the first try.
