Abstract

In this paper, a bended differential transmission line using the L-shaped pad is proposed to suppress the differential-mode noise. The bended differential transmission line using the L-shaped pad can reduce the differential-to-common mode conversion from -6.58 dB to -10.10 dB and the TDR differential-mode noise from 0.087 V to 0.023 V as compared with the bended differential transmission line using the parallel-plate capacitor. In order to verify the simulation results, measurement is done in the frequency and time domains where the measurement results are in good agreement with the simulation results.
