Tunable floating active inductor with internal offset reduction

Presented is a transistor-level implementation of a floating and tunable CMOS active inductor. It is based on the classical gyrator-C topology and is enhanced by adding an internal offset reduction mechanism to guarantee functionality also for unbalanced DC conditions. The realised inductance can be programmed for values between 685 mu H and 12.4 mH and is designed to be implemented using standard CMOS technology. Its range of operation is from 250 to 750 kHz and the inductor consumption does not exceed 2 mW.
