An ideal op-amp differentiator produces an output proportional to?

  • AThe integral of input voltage
  • BThe rate of change of input voltage with inversion
  • CThe square root of input voltage
  • DA constant independent of input
Report an error
Correct Answer: B. The rate of change of input voltage with inversion
Explanation: For the ideal inverting differentiator, Vo = -RC(dVin/dt), so output is proportional to the input's time derivative with inversion.
Reference: Standard analog electronics: op-amp differentiator
