Design a voltage follower output stage and add a voltage dro

Design a voltage follower output stage and add a voltage drop to get less than 100mV DC offset. Then calculate the voltage gain of the circuit.

Solution

The voltage follower with an ideal op amp gives simply

V_out=V_in

The voltage follower is often used for the construction of buffers for logic circuits.

so the gain is nothing but ouput voltage/input voltage so its nothing but unity.
