Abstract

Terminating transmission lines at either the source or the load side with a damping resistor is often used to improve the signal integrity of clock or control lines on PCBs. While a number of termination variants may produce similar results in respect to signal integrity the EMC performance can differ due to a different current and voltage distribution along the line. This paper investigates the impact of transmission line terminations on radiated emissions
