Inverting Operational Amplifier

Inverting Opm, An inverting amplifier (also known as an inverting operational amplifier or an inverting op-amp) is a type of operational amplifier circuit which produces an output which is out of phase with respect to its input by 180.Here we apply the input signal to the inverting terminal of the op-amp via the resistor R1. We connect the non-inverting terminal to ground. Further, we provide the feedback necessary to stabilize the circuit, and hence to control the output, through a feedback resistor R2. The voltage gain of the inverting operational amplifier or inverting op amp is Av = -(Rf/Ri)
