ABSTRACT:
A broadband microwave active inductor circuit for producing a flat inductive response versus frequency comprises a pair of bipolar transistors arranged in a gyrator configuration for producing an active inductance. Because the transistors exhibit intrinsic characteristics which influence the inductive response of the active inductor circuit, a feedback network is connected to the gyrator configuration to compensate for the intrinsic characteristics of the transistors so that the active inductor circuit realizes a flat inductive response over a wide range of frequencies including microwave frequencies.
