Differential amplifier with two OP Amps Figure (a) shows the schematic diagram of a differential amplifier with two OP Amps Figure (a) Differential amplifier with two OP Amps. The output V'o, due to the first stage is: Using Superposition theorem to the second state having V1 and V'o, the output voltage Vo can be written as:
Since R1 = R3 and Rf = R2, therefore,
The gain is same as non-inverting amplifier. | |
