WebThe op amp in the noninverting amplifier circuit shown has an input resistance of 400 kΩ, an output resistance of 5 kΩ, and an open-loop gain of 20,000. Assume that the op amp is … WebAs frequency increases, the open loop gain of the op amp drops. Also, reactive components and time delays will cause phase shifts. If the phase shift, including the op amp inversion, reaches 360 degrees and the gain is greater than 1, the loop will oscillate since the feedback is now positive.

"The open-loop gain of an electronic amplifier is the gain obtained when no overall feedback is used in the circuit. The open-loop gain of many electronic amplifiers is exceedingly high (by design) – an ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around , or 100 dB. " - Open loop gain of inverting op amp
