New grounded inductor simulator using unity gain cells

Abstract

A new grounded inductor simulator employing unity gain cells with X terminal intrinsic resistors and a capacitor is proposed in the present paper. It has two voltage followers with X terminal intrinsic resistors, one current follower with X terminal intrinsic resistor and one floating capacitor which can be easily implemented in now-a-days technologies. Also, the inductance of the proposed simulated inductor can be adjusted externally by changing control voltages; accordingly, it is suitable for integrated circuit fabrication. Simulation and experimental test results are included to verify the claimed theory.
