Abstract :
An alternative implementation for emulating an active inductor is proposed. Based on a classical gyrator active inductor architecture, the new active inductor is implemented by using a log-domain current integrator instead of a voltage integrator. Inductance and Q-factor can be tuned independently Simulation results confirming the idea are shown. The proposed circuit is a micropower active inductor operating in the weak inversion region of the MOSFETs
