Extended Equivalent Circuit Model for Enhanced Substrate Modeling of Three-Port Inductors

This paper presents an extension to the equivalent circuit of a three-port inductor model, which enhances the quality factor accuracy by precisely considering the parasitic substrate losses caused by eddy current effects. The proposed equivalent circuit allows to correctly model the frequency dependence of the substrate admittances over a broad bandwidth. Furthermore, it is applied to an almost fully analytical component value extraction procedure and thus can be used for the generation of scalable inductor models.
