Graph of a typical Integrator Amp circuit (drawing redrawn by Ben Henry)

The circuit at right integrates the input voltage by using an amplifier.

" ; Provides negative feedback for low output impedance needs. But it also distorts the output."<ref>Quick Study "Electronics 1, Part 2"</ref>

The use of an integrator circuit is the opposite of a differentiator circuit. In other words, If you have a triangle wave input and you differentiate it you will get a square wave output. If you run the square wave as the input to an integrator circuit you will end up with the triangle wave for the output<ref>Scherz, P: Practical Electronics for Inventors 2nd ed, page 545. </ref>. The resistor () is used to provide feedback<ref>Feedback_in_Amplifiers</ref>. of the output DC voltage. Without this, circuit wouldn't perform as calculated because of the un-ideal conditions of real life.
