How is the difference voltage calculated in closed loop non-inverting amplifier?
A. Vid= Vo – Vf
B. Vid= Vin – Vf
C. Vid= Vo – Vin
D. Vid= Vf – Vin
Answer:A
How is the difference voltage calculated in closed loop non-inverting amplifier?
A. Vid= Vo – Vf B. Vid= Vin – Vf C. Vid= Vo – Vin D. Vid= Vf – Vin
Explanation: Although, the input is given to the non-inverting terminal of op-amp, the difference voltage is equal to the input voltage minus feedback voltage is Vid= Vin – Vf.
