Chapter 1

Grounding and Wiring


A fundamental property of any electronic or electrical circuit is that the voltages present within it are referenced to a common point, conventionally called the ground. This term is derived from electrical engineering practice, when the reference point is often taken to a copper spike literally driven into the ground. This chapter describes the strategies that can be adopted for effective grounding to mitigate any potential electromagnetic compatibility issues, reduce noise, and improve circuit performance.
