What are open-loop and closed-loop gains of an op-amp?

WebOct 10, 2012 · The closed loop gain can be calculated if we know the open loop gain and the amount of feedback (what fraction of the output voltage is negatively fed back to the input). The formula is this: A c l o s e d = A o p e n 1 + A o p e n ⋅ F e e d b a c k The open-loop gain affects the performance generally like this. Firstly, look at the above formula. Webloop gain, the DC closed-loop gain of the non- inverting configuration is reduced to OL_DC OL_DC CL_DC(ideal) A OL_DC A1 A lim . →∞1A = = +b× b (6) In other words, the DC closed-loop gain is entirely determined by the external feedback network.
