Measure, simulate, and model power distribution networks (PDNs) accurately and efficiently with this new, cutting-edge resource. Frequency-domain analysis has revolutionized component design, and this book shows you, step-by-step, how to accurately characterize PDN components in the frequency domain including vias, bypass capacitors, planes, DC-DC converters and systems. Guiding you through the many alternatives to characterizing PDNs, it helps you to improve accuracy by choosing the right technique and avoiding the common pitfalls. Practical examples point out the strengths and weaknesses of simulation tools as well as explain setting parameters and options. The book presents best practices for measuring that aid you in the selection of calibration processes, instruments, probes, and cables. You learn how to use frequency-domain simulations and measurements to model printed-circuit board elements, including vias, planes, bypass capacitors, inductors, and DC-DC converters. Over 300 illustrations and more than 150 equations support key topics throughout the book.
