Abstract

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.
