WebThe Inverting Operational Amplifier configuration is one of the simplest and most commonly used op-amp topologies. The inverting operational amplifier is basically a constant or fixed-gain amplifier producing a negative output voltage as its gain is always negative. We saw in the last tutorial that the Open Loop Gain, ( A VO ) of an operational ... WebFigure 1: Op-amp Circuit. The fundamental function of an op-amp is to greatly amplify the differential between the two inputs, and output the result. If input at V (+) is greater than at V (−), the op-amp will amplify and output a positive signal; if V (−) is greater, the op-amp will output an amplified negative signal.
