An efficient partition analysis for electromagnetic interference estimation of high-speed input/output differential interfaces

To estimate electromagnetic interference (EMI) results of differential high-speed input/output interfaces more quickly, an partition method is proposed by separating system into source generation part and radiation part. Also, the partition analysis can help find contribution of differential-mode (DM) and common-mode (CM) to the unwanted radiation. A measurement validation on HDMI assesses the computational efficiency of proposed analysis by comparing with that of conventional full-wave simulation.
