How Return Path Discontinuity Creates EMI EMC Problems in High Speed PCB
Return path discontinuity (RPD) is a primary cause of EMI EMC problems in high speed PCB designs, directly increasing loop area and common-mode radiation. 1. The Physics of Return Path Discontinuity in High Speed PCB 1.1 What is a Return Path in High Speed PCB? Every signal on a high speed PCB trace requires a…
