Bended differential transmission line using balanced model for common-mode noise suppression

In this paper, a bended differential transmission line using the balanced model is proposed to efficiently reduce the common-mode noise. The bended differential transmission line using the balanced model can greatly reduce the mode conversion from ™5.47 dB to ™14.86 dB and the TDT common-mode noise from 0.068 V to 0.023 V as compared with the bended differential transmission line using the right-angle bend. 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.
