Differential pairs may gradually replace single trace as the media transmitting high-speed signal on high-speed digital circuit. This dissertation investigates the impact on electromagnetic radiation from high-speed circuit board by the distance between differential traces and edge effect .At the same time, we use the result of measurement and simulation to make sure the measurement method correct .The result shows that,the shorter the distance is,the lower the EMI of differential pairs have .The edge effect will has the ability of destroying the suppression of EMI.
Based on the consideration of measuring correctly, we use a solid kind of measurement method to search some non-ideal effects before studying EMI from differential pairs .These effect may exist on real measurement or ideal simulation. We hope to understand the environment of measurement as clearly as possible.
In addition, we address one simple and fast method to investigate radiation mechanism that resulted from edge effect of differential pairs.By this method to calculate radiation, we will understand more and more the radiation mechanism.
