An efficient SPICE model for lossy and dispersive coupled transmission lines

A simple circuit model for the time domain study of multiconductor transmission lines with CAD standard software such as SPICE is presented. The model consists of a group of decoupling networks, implemented with dependent voltage and current sources, which are obtained from a nodal analysis in the frequency domain and decoupled dispersive lines. These lines are modeled with ordinary lossless TEM lines and analog filters, which are designed to have the required propagation characteristics.<
