A Two-Layer Board Intellectual Property to Reduce Electromagnetic Radiation

Many papers proposed the analyses for the effects of signal trace passing over the split ground in the packages or PCBs. However, few papers presented how to reduce the excessive radiation caused by the non-ideal return path in 2-layer PCBs.

In this paper, a PCB layout technique is proposed to maintain ideal return paths for high-speed traces routing. Our goal is to implement and verify the digital LCD-TV in 2-layer PCB including the high-speed memory interfaces with less electromagnetic radiation using S-parameters simulation and EMI measurement..
