摘要

本論文針對玻璃纖維效應對於差模帶線所產生之速度差異，提出改善玻璃纖維所產生的速度差異之共模雜訊抑制方法。此論文提供的抑制方法是利用玻璃纖維與差模帶線的相對位置，減少玻璃纖維對於差模帶線之速度差，從而降低時序不同步所產生的共模雜訊，如何利用玻璃纖維與差模帶線的相對位置來抑制也是本論文的一大重點，藉由分析差模帶線不同位移量的參數與玻璃纖維轉角度的方向對於共模雜訊的影響，最終整理出比較圖表。

In this paper investigates on the difference in speed produced by the fiberglass weave to the differential strip line, a common mode noise suppression method is proposed to improve the speed difference produced by the fiberglass weave. The suppression method provided in this paper is to use the relative position of the fiberglass weave and the differential strip line to reduce the speed difference between the fiberglass weave and the differential strip line, thereby reducing the common mode noise generated by the timing asynchronous. How to use the relative position of the fiberglass weave and the differential strip line to suppress is also a major focus of this paper. By analyzing the influence of the different displacement parameters of the differential strip line and the direction of the fiberglass weave rotation angle on the common mode noise, a comparison chart is finally compiled.
