Return Current Design
Chapter
Abstract
Many EMI problems associated with high-speed circuits are due to improper design of the return current path. PCB designers often expend considerable effort to carefully design traces with the proper length, proper transmission line impedance, etc., but neglect the return current path that completes the current loop. These EMI problems can usually be avoided if attention is paid to this return current path.
