Operational amplifiers often require an external feedback circuit in practical applications. Because the open-loop gain of the op amp is very high, and the gain required in practical applications is not very high, it is necessary to add a negative feedback circuit to form a closed loop to obtain the corresponding function. In addition, the performance of the op amp is greatly improved under deep feedback conditions.
