Power Integrity

A series of cogently written articles by 49 industry experts, this collection fills the void on Power Distribution Network (PDN) design procedures, and addresses such related topics as DC–DC converters, selection of bypass capacitors, DDR2 memory systems, powering of FPGAs, and synthesis of impedance profiles. Through these contributions from such leading companies as Sun Microsystems, Sanyo, IBM, Hewlett-Packard, Intel, and Rambus, readers will come to understand why books on power integrity are only now becoming available to the public and can relate these topics to current industry trends.

The First Comprehensive, Example-Rich Guide to Power Integrity Modeling Professionals such as signal integrity engineers, package designers, and system architects need to thoroughly understand signal and power integrity issues in order to successfully design packages and boards for high speed systems. Now, for the first time, there's a complete guide to power integrity modeling: everything you need to know, from the basics through the state of the art. Using realistic case studies and downloadable software examples, two leading experts demonstrate today's best techniques for designing and modeling interconnects to efficiently distribute power and minimize noise. The authors carefully introduce the core concepts of power distribution design, systematically present and compare leading techniques for modeling noise, and link these techniques to specific applications. Their many examples range from the simplest (using analytical equations to compute power supply noise) through complex system-level applications. The authors Introduce power delivery network components, analysis, high-frequency measurement, and modeling requirements Thoroughly explain modeling of power/ground planes, including plane behavior, lumped modeling, distributed circuit-based approaches, and much more Offer in-depth coverage of simultaneous switching noise, including modeling for return currents using time- and frequency-domain analysis Introduce several leading time-domain simulation methods, such as macromodeling, and discuss their advantages and disadvantages Present the application of the modeling methods on several advanced case studies that include high-speed servers, high-speed differential signaling, chip package analysis, materials characterization, embedded decoupling capacitors, and electromagnetic bandgap structures This book's system-level focus and practical examples will make it indispensable for every student and professional concerned with power integrity, including electrical engineers, system designers, signal integrity engineers, and materials scientists. It will also be valuable to developers building software that helps to analyze high-speed systems.

Consistently Design PDNs That Deliver Reliable Performance at the Right Cost Too often, PDN designs work inconsistently, and techniques that work in some scenarios seem to fail inexplicably in others. This book explains why and presents realistic processes for getting PDN designs right in any new product. Drawing on 60+ years of signal and power integrity experience, Larry Smith and Eric Bogatin show how to manage noise and electrical performance, and complement intuition with analysis to balance cost, performance, risk, and schedule. Throughout, they distill the essence of complex real-world problems, quantify core principles via approximation, and apply them to specific examples. For easy usage, dozens of key concepts and observations are highlighted as tips and listed in quick, chapter-ending summaries. Coverage includes • A practical, start-to-finish approach to consistently meeting PDN performance goals • Understanding how signals interact with interconnects • Identifying root causes of common problems, so you can avoid them • Leveraging analysis tools to efficiently explore design space and optimize tradeoffs • Analyzing impedance-related properties of series and parallel RLC circuits • Measuring low impedance for components and entire PDN ecologies • Predicting loop inductance from physical design features • Reducing peak impedances from combinations of capacitors • Understanding power and ground plane properties in the PDN interconnect • Taming signal integrity problems when signals change return planes • Reducing peak impedance created by on-die capacitance and package lead inductance • Controlling transient current waveform interactions with PDN features • Simple spreadsheet-based analysis techniques for quickly creating first-pass designs This guide will be indispensable for all engineers involved in PDN design, including product, board, and chip designers; system, hardware, component, and package engineers; power supply designers, SI and EMI engineers, sales engineers, and their managers.
