## Op-Amp Application: Inverting Amplifier

The figure below show an operational amplifier circuit. Closed-loop gain given by this circuit is R2/R1 when this ratio is small compared with the amplifier open-loop gain, and it’s called as inverting circuit. The value of input impedance is equal to R1. Bandwidth of this closed-loop is equal to the unity-gain frequency divided by one plus the closed-loop gain. Take […]
