Distributed modeling of devices and interconnections through advanced LE-FDTD algorithm26th European Microwave Conference, 1996

A mixed-mode circuit simulation technique is presented, based on the lumped-element FDTD scheme. The algorithm is extended to accomplish numerical, as well as analytical, models of lumped devices. Device behavior can thus by directly linked to technological parameter, without requiring the formulation and characterization of an equivalent circuit. Application of numerical and analytical lumped device models to the analysis of small-size electronic circuits are discussed. The practicality of LE-FDTD approach for TCAD circuit optimization is thus demonstrated.
