The use of negative feedback in op-amp
WebJun 11, 2024 · Op-amp Negative feedback finds use mainly in amplifiers, where the input is multiplied by a factor called gain, and the output should be linear and stable with changes … WebJul 5, 2024 · To achieve stable operation, op-amps are used with negative feedback. The gain of an op-amp without feedback is called the open-loop gain whereas the gain of an op-amp with a feedback circuit is called the closed-loop gain. The open-loop gain halves when frequency doubles.
