In this paper, a novel adaptive stopping criterion for FDTD simulations of microwave components is applied to a package example. The new stopping criterion relies on the Vector Fitting algorithm to successively build an updated macromodel for the frequency response of the device under study based on increasing time-limited transient responses. In this way, it aims at minimizing the number of timesteps...
Rational approximation of frequency responses is important for the modeling and design of microwave systems. An exact match of the dc value is crucial to ensure the accuracy and reliability of circuit and system simulations. This paper presents a novel approach to compute dc-compliant macromodels that are both accurate and uniformly passive at the same time. Several examples illustrate the effectiveness...
