An op-amp has an input offset voltage of 1 mV and a noise gain of 101. Ignoring other errors, the output offset contribution is approximately?

  • A1 mV
  • B10.1 mV
  • C101 mV
  • D1.01 V
Report an error
Correct Answer: C. 101 mV
Explanation: Output offset due to input offset is approximately noise gain times Vos: 101×1 mV=101 mV.
Reference: Standard analog electronics: input offset voltage
