Abstract A novel scheme to suppress the remnant mode conversion noise with a surface mount device (SMD) capacitor on dual back-to-back bent differential lines is proposed. To suppress the remnant mode conversion noise, an additional SMD capacitor is loaded on the differential lines between two bends to equalize even- and odd-mode velocities. The mode conversion noise suppression characteristics of the proposed scheme were analyzed and compared with various schemes. Also, eye diagrams confirmed that the addition of the SMD capacitor suppressed remnant mode conversion noise while preserving differential signal quality in dual back-to-back bent differential lines.

使用表面贴装器件电容器的残余模式转换噪声抑制

摘要 提出了一种在双背靠背弯曲差分线上使用表面贴装器件（SMD）电容器抑制残余模式转换噪声的新方案。为了抑制残余模式转换噪声，在两个弯曲之间的差分线上加载了一个额外的 SMD 电容器，以均衡偶模和奇模速度。分析了所提出方案的模式转换噪声抑制特性，并与各种方案进行了比较。此外，眼图证实添加 SMD 电容器可抑制残余模式转换噪声，同时保持双背对背弯曲差分线路中的差分信号质量。
