An op-amp has an input offset voltage of 2 mV and is used with a closed-loop noise gain of 50. Ignoring other errors, the output offset contribution is approximately?

  • A0.04 mV
  • B2 mV
  • C100 mV
  • D2 V
Report an error
Correct Answer: C. 100 mV
Explanation: The input-referred offset is amplified by the circuit's noise gain, giving about 2 mV × 50 = 100 mV.
Reference: Standard analog electronics: input offset voltage
