Inverting Op-Amp and the Concept of Virtual Ground

Inverting Op-Amp Configuration: As discussed in the previous article, the op-amp is a very high gain differential amplifier. In the open-loop configuration, the typical gain of the op-amp is 105 to 106  Fig. Operational Amplifier Because of high open-loop gain, even for a small differential input between the two terminals, the output of the op-amp will … Read moreInverting Op-Amp and the Concept of Virtual Ground
