Integrator

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."1

The use of an Integrator circuit is the opposite of a Differentiator circuit. In other words, If you have a "^^^" style input and you Differentiate it you will get a "square sine wave" output. If you run the "square sine wave" as the input to an Integrator circuit you will end up with the "^^^" for the output2. The Resistor () Is used to provide feedback3 of the output DC voltage. Without this, circuit wouldn't perform as calculated because of the un-ideal conditions of real life.
