CIRCUITS LABORATORY EXPERIMENT 9 Operational Amplifiers
Figure 9.4: Operational amplifier connected as a voltage follower voltage follower of Figure 9.4. The input voltage is Vi,. The virtual short forces v-= v+ and, therefore, Vo = Vi. Hence, it is termed a voltage follower. Now you may be thinking that this is a circuit that serves no function since the output voltage merely equals the input voltage.
