This circuit shows one section of an LM3900 that is used to form a difference integrator. In addition to being the basis for many sweep circuits, this circuit can also provide the time integral of the difference between two input waveforms. This is useful for dc feedback loops because both the comparison to a reference and the integration occur in one amplifier. National Semiconductor linear Applications Handbook 1991 p 248
