The Voltage Follower Circuit of The Operational Amplifier

The Voltage Follower Circuit of The Operational Amplifier

The voltage follower circuit of the op amp, as shown in Figure 1, uses virtual short and virtual break. At first glance, it seems simple and clear. If you think that there is not much content to pay attention to, then you may be wrong. Understanding the op amp’s voltage-following circuit is a great help for understanding the op amp’s in-phase, inverting, differential, and various op amp circuits.
