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 aN state-of-the-art circuit simulators. Recently passive closed-form optimal matrix-rational approximation based algorithm is developed for macromodeling of lossy multiconductor transmission lines. This paper presents three case studies for optimal matrix rational approximation and provides the performance comparison with the conventional lumped discretization.
