Abstract :
This study investigates how common-mode noise (CMN) is generated and reduced for the differential traces with adjacent ground lines were connected to a ground plane. Based on the resonant effects of ground line and parallel ground planes, the CMN generation mechanism is studied. Based on the analysis of the generation mechanism, a simple design guideline for CMN reduction is proposed for the differential traces with adjacent ground lines were connected to a ground plane.
