A Spice Model for Multiple Coupled Microstrips and Other Transmission Lines

摘要

A general multiple coupled line model compatible with standard CAD programs, such as SPICE, is presented. It is shown that the model can be used to help analyze and design coupled line (e.g., microstrip) circuits with linear, as well as non-linear/ time varying terminations, and to help study the pulse propagation characteristics in high speed digital and optical circuits.
