Grounded inductance circuit using gyrator circuit

Abstract

The grounded inductance circuit utilizing a gyrator circuit includes a first operational transconductance amplifier, a second operational transconductance amplifier and a first capacitor. A first output terminal of the first operational transconductance amplifier is connected to a first input terminal of the second operational transconductance amplifier, and a second output terminal of the first operational transconductance amplifier is connected to a second input terminal of the second operational transconductance amplifier. A first output terminal of the second operational transconductance amplifier is connected to a second input terminal of the first operational transconductance amplifier and a second output terminal of the second operational transconductance amplifier is connected to a first input terminal of the first operational transconductance amplifier. The second input terminal of the first operational transconductance amplifier and the first input terminal of the second operational transconductance amplifier are connected to each other and the junction of the two input terminals is applied with a predetermined dc bias voltage with respect to the ground potential. The capacitor is connected between the junction and the second input terminal of the second operational transconductance amplifier. An ac signal is applied between the first input terminal of the first operational transconductance amplifier and the ground potential.
