The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.
The construction of simple Integrator circuit using op-amp requires two passive components and one active component. The two passive components are resistor and capacitor. The Resistor and the Capacitor form a first-order low pass filter across the active component Op-Amp. Integrator circuit is exactly opposite of Op-amp differentiator circuit.
The general formula for the output voltage of an integrator op-amp circuit, -1/ (R1 * Cf) times the integral of the input voltage, where R1 is the input resistor and Cf is the feedback capacitor, reveals the precise relationship between the components and the resulting output.
The electronic circuit formed by the op-amp, resistor, and capacitor acts as an integrating amplifier, accurately reflecting the integral of the input voltage in its output. The functionality of the integrator circuit is a marvel of electronic engineering.
The output current obtainable from an integrated-circuit operational amplifier is limited by the relatively small geometry of the output transistors and by the low power dissipation of a small chip. These limitations can be overcome by following the amplifier with a separate output stage.
Therefore, an op-amp based integrator can perform mathematical integration with respect to time. The integrator produces an output voltage across the op-amp, which is directly proportional to the integral of the input voltage; therefore the output is dependent on the input voltage over a period of time.
