Abstract

In this study, we present an accurate and efficient analysis technique of frequency-dependent transmission line system using scattering parameters. First, low-order rational approximations of the scattering parameters are derived over a wide frequency range using robust interpolation technique. An appropriate reference system is also chosen to make the scattering waveforms smooth and simple. Then, the low-order rational approximations of the scattering parameters are directly implemented in conventional time-domain simulator using recursive convolution. To validate the accuracy and the efficiency of the method, the transient analyses of a coaxial cable with skin-effect parameters and an interconnect network with a component characterized by measured scattering parameters are presented.
