印刷电路板上的波形失真是高频信号传输中的一个严重问题。为了克服这个问题，我们已经提出了分段传输线（STL）。STL将传输线划分为具有不同线宽的多个段，这些段被调整以通过在段边界处发生的反射波的叠加来重塑信号波形。在之前的工作中，我们一次仅在与设备连接的传输线中的一个点处重塑波形。本文扩展了在器件的两个点上同时进行波形整形的方法。利用该方法设计了一个高速计算机DIMM时钟线，并验证了该方法的有效性。
Distortion of the waveform on printed circuit board (PCBs) is a serious problem in higher-frequency signals transmission. To overcome this problem, we have already proposed segmental transmission line (STL). The STL divides transmission lines into multiple segments with different line widths, those are adjusted to reshape the signal waveform by superposition of reflected waves occurring at segment boundaries. In the previous work, we reshaped the waveform at only one point in the transmission line connected with a device at a time. This paper expands the method to reshape the waveform at two points of the devices at a time. We design a DIMM (dual in-line memory module) clock-line for high-speed computers using our new method, and show effectiveness of the method.
