PCB Ground Design: How to Reduce Noise, EMI, and Ground Bounce

Introduction One of the most important parts of PCB design is also one of the most frequently misunderstood:  Ground. Many engineers initially think of ground as simply a connection to 0 V. In a real PCB, however, ground is also a current-return path. When current flows through a PCB trace, plane, via, connector, or cable, the resistance […]
