A derived physically expressive circuit model for integrated passives in RFIC

Abstract

A systematic derived circuit model for integrated passives in RFICs is presented in this paper. This generic concise circuit model represents clear physical meaning and can be easily plugged into the RFIC design flow. As demonstration examples, the physically meaningful circuit models of a section of coplanar waveguide (CPW) and a square spiral inductor fabricated using 0.18 mum CMOS process are derived. Excellent agreement of the Q performances and the frequency responses of the derived circuit model with those from the measurements can be observed over the frequency range from 0.45 GHz to 10 GHz, demonstrating the validity and the usefulness of this new circuit model extraction approach.
