Abstract

In this paper, a bended differential transmission line using a compensation inductance is proposed to efficiently suppress the common-mode noise. The bended differential transmission line using the compensation inductance can then be implemented by the bended differential transmission line using the short-circuited coupled line. It has been shown that the bended differential transmission line using the short-circuited coupled line can greatly reduce the mode conversion from -5.47 to -14.75 dB, and the time-domain-through common-mode noise from 0.068 to 0.02 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.
