Passive SPICE-compatible models of dispersive interconnects

In this paper, the modal network theory of the skin effect is used for the development of discrete models for dispersive, multiconductor interconnects compatible with passive model order reduction algorithms. With the introduction of properly defined auxiliary variables, a passive discrete form of Telegrapher´s equations is obtained. The resulting discrete model is then used in conjunction with the passive reduced-order interconnect modeling algorithm (PRIMA) for the generation of low-order, multi-port macromodels for interconnection networks. Numerical examples are used to demonstrate the proposed methodology and the associated computer implementation
