Design Practices for POWER INTEGRITY in Printed Circuit Boards

摘要

Power is one of the most important challenges in designing printed circuit boards. Power requirements depend on the application, be it medical equipment, automobiles or consumer electronics. Power integrity is the analysis to check whether the desired voltage and current from the source gets delivered to the load. This includes simulation to validate whether the power distribution network (PDN) maintains a proper DC voltage level at the loads, and the impedance between power and ground is minimal for the appropriate frequency range, so it is well below the target impedance.
