Abstract

An exact model of a lossless multiconductor transmission line (MTL) is presented. The model is directly implementable in the SPICE code. It is therefore more readily available for use than a specially designed FORTRAN code. It is also an exact solution of the MTL equations, whereas most specially designed time-domain FORTRAN codes are approximate solutions. Implementation of the model in a SPICE code allows the incorporation of nonlinear terminations already present in SPICE. Therefore, a wide variety of electronic-circuit design problems can be investigated, and the actual crosstalk in a particular conductor interconnection pattern can be investigated. The model is suitable for use in the personal computer versions of SPICE; the predictions were obtained on an IBM PC AT using the demo version of PSPICE.
