Two Proportional Amplifying Circuit Schemes of Operational Amplifier

An operational amplifier, which has two input pins and one output pin. Two of the input pins, one is the positive input and the other is the negative input. It is precisely because operational amplifiers have positive-phase input and negative-phase input that engineers are developing proportional amplifier circuits with operational amplifiers, and there are two […]
