Seeing is Believing (Inductance in PCBs)

Abstract

Typical university education focuses on ‘inductors’ not ‘inductance’. However, it is the inductance that determines the EMC and Power Integrity (PI) performance and to some degree, inductance affects signal integrity (SI). When inductance is discussed, there is usually a number of equations, equivalent circuits, and even simulations, etc. to try and help the student understand the concept of inductance.
