Abstract

The frequency responses of two widely used active inductor topologies are analyzed and compared using a generalized circuit model for the active devices in the circuits. A very wideband active inductor in CMOS was subsequently fabricated and tested and the inductor exhibits a measured self-resonant frequency of 9.7 GHz.
