What happens if R1>>RF in the circuit
A. Some amount of output offset voltage is present
B. Some amount of input offset voltage is present
C. Some amount of gain voltage is present
D. All of the mentioned
Answer:A
What happens if R1>>RF in the circuit
A. Some amount of output offset voltage is present B. Some amount of input offset voltage is present C. Some amount of gain voltage is present D. All of the mentioned
Explanation: If R1 >>RF, the gain Aoo≅1, which makes Voo ≅ Vio. Thus, all op-amp circuit has some output offset voltage.
