Abstract

In this paper, a bended differential transmission line using a short-circuited coupled line is proposed to efficiently suppress the common-mode noise. 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 dB to −14.75 dB and the TDT common-mode noise from 0.068 V 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.

弯曲差动传输线采用短路耦合线进行共模噪声抑制

为了有效地抑制共模噪声，本文提出了一种采用短路耦合线的弯曲差动传输线。结果表明，与采用直角弯曲的差分传输线相比，采用短路耦合线的弯曲差分传输线可以将模式转换从−5.47 dB降低到−14.75 dB，将TDT共模噪声从0.068 V降低到0.02 V。为了验证仿真结果，在测量结果与仿真结果吻合较好的频域和时域进行了测量。
