Fundamentals of EMI Simulation
Isaac Waldron
Abstract
EMI continues to be a challenging problem for electronics systems but preventing it is no longer the trial and error process it once was. Proper signal and power integrity are crucial to first pass chamber success, and simulation tools that can solve these problems are now in common use. This presentation will provide an introduction to EMC and the root causes of EMI related to package and PCB design. Capacitor placement, plane impedance, current return path and common mode conversion will be discussed. Various simulation and measurement results from real world designs will be shown.
