Finite gain
WebOct 7, 2024 · There is also a general formula for op-amps when open-loop gain is not infinite. The formula is: Gain, G = Gideal * ( A / (A + 1 + R2/R1)) Where R2 is the feedback resistor, R1 is the other resistor, A is the open-loop gain. This also holds true for non-inverting op-amps.

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 …
WebFinite gain — the effect is most pronounced when the overall design attempts to achieve gain close to the inherent gain of the FDA. Finite input resistance — this puts an upper bound on the resistances in the feedback circuit. Nonzero output resistance — important for low resistance loads. Except for very small voltage output, power ... WebMay 22, 2024 · Since condition 1 requires equality between V a, and V i, the ideal closed-loop gain is V o V i = Z 1 + Z 2 Z 1 The conditions can be used to determine ideal values for characteristics other than gain. Consider, for example, the input impedance of the two amplifier connections shown in Figure 1.2.
