Grounded Inductor Simulation Using a Non-inverting Voltage-controlled Voltage Source

Abstract

An active RC circuit consisting of a non-inverting amplifier, two resistors and a capacitor is presented for the simulation of a grounded inductor. The inductance and its associated resistance are found to be frequency independent, while the Q factor of the inductor can be made quite high. The inductance can be conveniently varied by the variation of the capacitance. Experimental results show excellent agreement with the theoretical values.
