✦ Synopsis

In this paper we describe a CAD tool for modeling and designing thin-film inductors and transformers within a circuit simulation environment. The model for the thin-film inductor takes into account the distributive nature of the inductor; i.e. the resistance of the metal, the capacitance of the oxide, line to line capacitance, the resistance of the substrate, the capacitance to the substrate, and the inductance and mutual inductance of the metal lines. The model is compared with experimental results obtained from CMOS inductors and shows good agreement.
