Lossy transmission line passive macromodeling algorithm - three case studies

The rapid increase in operating speeds, density and complexity of modern integrated circuits has made interconnect analysis a requirement for all state-of-the-art circuit simulators. Recently, a passive closed-form optimal matrix-rational approximation based algorithm has been developed for macromodeling of lossy multiconductor transmission lines. This paper presents three case studies for optimal matrix rational approximation and provides a performance comparison with the conventional lumped discretization.
