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.
l型衬垫差模噪声抑制
本文提出了一种采用l型衬垫的弯曲差动传输线来抑制差模噪声。与采用并联极板电容的弯曲差动传输线相比,采用l型焊盘的弯曲差动传输线的差共模转换从-6.58 dB降低到-10.10 dB, TDR差模噪声从0.087 V降低到0.023 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。
