Abstract

A simple yet accurate method of modeling the spiral inductor up to six times its first self-resonant frequency is presented. The prosed model, which is derived from the measured data with lumped elements, overcomes the limitation in the valid frequency range of the commonly adopted PI- model and the difficulty in the extraction of element values of broadband model consisting of a number of PI-model cascaded together. Its element values are extracted via systematic data fitting, with two element values to be varied at a time. Such systematic approach offers easy extension of its validity to a higher frequency without complicating the extraction methodology.
