WebOpen 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 from about 20,000 to 200,000. Weban example, an op amp with an open-loop gain of 106 dB can be written in terms of V/V as OL_DCdB A 106 dB 20 20 OUT OL_DCV/V ERR V V A 10 10 199,526 .

WebSep 23, 2024 · if I use an open loop op-amp as comparator, v+ and v− can have significantly different values, so vd=v+−v− wouldn't be equal (or tending) to zero. Yes, that is correct. In order to have vd = 0 (more precise: almost zero) you will need to add a feedback loop with negative feedback around the opamp. – Bimpelrekkie Sep 23, 2024 at 14:18 2 WebThe Gain of Real Op-Amps The open-circuit voltage gain A op (a differential gain!) of a real (i.e., non-ideal) operational amplifier is very large at D.C.
