Reduced Order Electromagnetic Models for On-Chip Passives Based on Dual Finite Integrals Technique

Abstract

To solve field-circuits coupled problems, the electromagnetic field equations are discretized by the dual finite integration technique (dFIT), a numerical method which allows the accuracy control of the extracted parameters. Several techniques are used to accelerate the extraction process, such as minimal virtual boundary, minimal mesh and minimal frequency samples set. The behavior of the synthesized SPICE model extracted with proposed algorithm, in the case of passive on-chip devices placed on silicon substrate shows good agreement with respect to the measurements
