A reflectance-based computer aided modelling tool for high speed/high frequency communication systems

Abstract

A reflectance-based method is presented to model the measured or computed data, obtained from a "passive one-port physical device" by means of its Darlington equivalent. The basis of the new modelling tool rests on the numerical generation of the scattering parameters of the Darlington 2-port from the given reflectance employing the losslessness condition. The proposed technique does not require any choice for the circuit topology to build the model. The circuit topology is the natural consequence of the modelling process.
