Transient analysis of coupled transmission lines characterized with the frequency-dependent losses using scattering-parameter based macromodel

摘要

This paper describes two novel macromodels for incorporating the single and coupled transmission lines characterized by the frequency-dependent losses into a scattering-parameter (S-parameter) macromodel based simulator. This approach computes the moments of the S-parameter based upon the frequency-dependent parasitic functions: R(f), L(f), C(f), and G(f) which characterize either the single or the coupled transmission lines. These same moments can be used later to construct the macromodels. Once the macromodels are built, the transient analysis can be performed by using the S-parameter based macromodel simulator.
