Principles of Power Integrity for PDN Design--Simplified: Robust and Cost Effective Design for High Speed Digital Products

Preface

The Focus of This Book

Power integrity is a confusing topic in the electronics industry—partly because it is not well-defined and can encompass a wide range of problems, each with their own set of root causes and solutions. There is universal agreement that the field of power integrity includes everything from the voltage regulator module (VRM) to the on-die core power rails and on-die capacitance.

Between the VRM and die are interconnects on the package and board, which often carry discrete capacitors with their associated mounting inductance. The power distribution network (PDN) refers to all interconnects (usually inductive), the intentional energy storage devices (usually capacitive), and loss mechanisms (damping) between the VRM ...
