✦ Synopsis

In designing high-speed pulse integrated circuits, it is necessary to clarify that the propagating waveform is affected by the multiple reflection caused by discontinuity and mismatching of the interconnected lines. In this paper, we present the modified central difference method with simple boundary treatments for solving Telegrapher's equations only in the time domain in which both voltage and current solutions are derived at the same time. As this algorithm has a compact structure and memory independent of time as compared with other algorithms, the transient phenomena including multiple reflection along the whole line can be represented dynamically. It is also available for the steady state. It is shown by simulation studies that in high-speed pulse transmission on microwave analog circuits and digital VLSIs, this technique is simple and useful in analyzing any type of propagating signals on uniform and various nonuniform transmission lines.
