Common-mode noise effect for differential traces adjacent ground lines connection a ground plane

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 analysi...

Summary: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.
