Abstract

"High Speed differential signals have become common place in the computer industry. While the use of differential signaling can significantly improve the signal integrity, it does not eliminate EMC concerns. Small amounts of rise/fall time mismatch, in-pair skew, or amplitude mismatch can create significant amounts of common mode signals, which, in turn, cause EMI emissions. Discrete common mode filters are not commonly used due to their impact on the intentional signal as well as their cost. Electromagnetic band gap (EBG) structures can filter unwanted common mode energy without reducing the signal integrity of the intentional signal."
