For an ideal op-amp integrator with input resistor R and feedback capacitor C, the output is proportional to?

  • AThe time integral of the input with inversion
  • BThe time derivative of the input without inversion
  • COnly the DC value of the input
  • DThe square of the input voltage
Report an error
Correct Answer: A. The time integral of the input with inversion
Explanation: An ideal inverting integrator produces Vo = -(1/RC) integral(Vin dt), within its intended operating range.
Reference: Standard analog electronics: op-amp integrator
