A CAD algorithm for RF/microwave interconnect modeling

Abstract

This article presents a numerical technique (CAD) to model and analyse interconnects encountered in the design of high speed/high frequency analog RF/microwave circuits with mixed, lumped and distributed elements to be implemented on-chip. In this method, the interconnect networks are modeled by lossless two-ports composed of simple lumped elements and commensurate transmission lines, which are defined by two-variable scattering functions. Two examples are given to describe the application of the proposed method in, the modeling of interconnects.
