摘要

在ghz域，PCB走线强烈要求高信号完整性(SI)。然而，传统的基于特性阻抗匹配的方法不能很好地应用于GHz数字信号。为了克服这个问题，我们已经提出了一种新的pcb走线结构，称为“分段在线传输(STL)”。在本文中，我们将STL应用于5ghz差分传输线，结果显示其在眼高和眼宽方面的SI提升率分别为3.38和1.7。

Signal-integrity improvement based on the segmental-transmission-line

In the GHz-domain, high signal-integrity (SI) is strongly demanded in PCB traces. Unfortunately, however, conventional techniques based on the characteristic-impedance-matching cannot work well in the GHz digital signals. In order to overcome this problem, we have proposed a novel PCB-trace structure called “Segmental-Transmission-Line (STL)” already. In this paper, we apply the STL to the 5 GHz differential transmission line and show its remarkable SI improvement ratios of 3.38 and 1.7 in the eye-height and eye-width, respectively.
