Common-mode noise reduction of right-angled coupled stripline using timing-offset differential signal

In this paper, a right-angled coupled microstrip line using the timing-offset differential signal is proposed. The right-angled coupled microstrip line using the timing-offset differential signal can greatly reduce the TDT common-mode noise from 68 mV to 26 mV as compared with the right-angled coupled microstrip line using zero timing-offset differential signal. In order to further reduce the TDT common-mode noise, a right-angled coupled stripline using the timing-offset differential signal is proposed. As compared with the right-angled coupled microstrip line using the timing-offset differential signal, the TDT common-mode noise is further reduced from 26 mV to 13 mV. In order to verify the simulation results, measurement is conducted in the time domain where the measurement results are in good agreement with the simulation results.
