Abstract
This paper focuses on investigating and modelling the impact of dummy fills on the performance of CMOS spiral inductors. A modified π-Model is proposed to account the dummy effect. A spiral inductor is fabricated on 9-metal 65nm CMOS technology. Dummy effect is evaluated through comparisons on parameter values in equivalent circuit model. Experiment shows the modified π-Model provides proper characterization on the inductor with dummy fills.
