GSSG Resonance Method for Interconnect Designs

By Davi Correia, Carlisle Interconnect; Michael Rowlands, Molex LLC; Alexandra Haser, Molex LLC

For many interconnect products, more than 50% of design time is spent on reducing resonances. This paper provides a basic electromagnetic understanding of resonant behavior, a method for quickly determining resonant frequencies, a secondary set of metrics to evaluate if a particular frequency is excited or not, and a set of examples.

Book Review: Principles of Power Integrity for PDN Design—Simplified
By Bert Simonovich

If you are looking for a good book to help you understand PDN design, then this book is a good place to start. In an Expert Advice column, Bert Simonovich, member of the SIJ Editorial Advisory Board, summarizes what you can learn in this mammoth 786 pages volume. The book is organized in such a way as to act as a training manual for the power integrity practitioner, read on to see what awaits you.
 

Advertisement Accurate and fast power integrity measurements By Rohde & Schwarz Measuring ripple, noise and transients on today’s low-voltage DC power rails challenges most oscilloscopes. With smaller rail voltages and 1 % to 2 % tolerances, instrument and probing noise make it hard to accurately measure specified tolerances. Adequate bandwidth is required to see harmonics of fast edges and higher frequency sources that can be coupled on power rails.
