Op amp limitations
Webaxes, respectively. Never assume that the op amp open-loop-gain curve is identical to the loop gain because external components have to be accounted for to get the loop-gain A aR RR G FG β= + curve. When R F = 0 and R G = ∞, the op amp reduces to a noninverting buffer amp (unity gain) and the loop gain becomes equal to the op amp open-loop ...

Open Loop Gain, (Avo) Infinite – The main function of an operational amplifier is to amplify the input signal and the more open loop gain it has the better. Open-loop gain is the gain of the op-amp without positive or negative feedback and for such an amplifier the gain will be infinite but typical real values range …
