A simple wide-band compact model and parameter extraction using particle swarm optimization of on-chip spiral inductors for silicon RFICs

Published: 17 April 2005 Publication History

Abstract

We propose a wide-band model of spiral inductor in which a resistance is incorporated in series with the overlap capacitance that estimates the underpass oxide leakage and a parallel combination of lateral substrate resistance and capacitance is introduced to model the lateral substrate coupling at high frequencies. The particle swarm optimization (PSO) algorithm is used for the extraction of the model parameters. The proposed model has been verified with the measured data of octagonal spiral inductors fabricated on a six-metal BiCMOS7 process. The model along with the PSO extraction procedure gives excellent fit when compared with the measured data over the frequency range up to 10GHz. The frequency independent elements of the model facilitate it to be integrated in a SPICE-compatible simulator.
