"An approach for the design of high-Q active inductor (AI) with high dynamic range is presented.

Abstract

"An approach for the design of high-Q active inductor (AI) with high dynamic range is presented. The proposed AI includes a passive variable phase- and amplitude-compensating network and a highly linear inverting amplifier, forming a gyrator-C architecture. The equivalent inductance and resistance values are tunable in a wide frequency range; outside the operating frequency band, the inductor equivalent resistance increases, improving signal rejection for band-pass filter applications. As a feasibility demonstration a first-order active band-pass filter using the high-Q active inductance has been fabricated and tested. The filter has a center frequency of 600MHz and a measured noise figure of 11dB with a 5dBm 1-dB compression point and a 82 dB dynamic range. "
