A circuit in which the output voltage waveform is the integral of the input voltage waveform is the integrator or Integration Amplifier Such a circuit is obtained by using a basic inverting amplifier configuration if the feedback resistor RF is replaced by a capacitor CF Integrator Circuit.
Operational Amplifier (OPAMP) Formulas and Equations
Opamp Integrator A circuit in which output voltage waveform is the time integral of the input voltage waveform is called integrator or integrating amplifier The following circuit shows a basic/ideal integrator using opamp.
2.8 Integrators and Differentiators
Operational amplifiers can be used as part of a positive or negative feedback amplifier or as an adder or subtractor type circuit using just pure resistances in both the input and the feedback loopExampleOperationMechanismDefinitionFunctionBut what if we where to change the purely resistive ( Rƒ ) feedback element of an inverting amplifier to that of a frequency dependant reactance ( X ) type complex element such as a Capacitor C What would be the effect on the opamps output voltage over its frequency range I.

An operational amplifier integrator circuit produces an output voltage which is proportional to the area (amplitude multiplied by time) contained under the waveform An ideal opamp integrator uses a capacitor Cf connected between the output and the opamp inverting input terminal as shown in the figure below.
