Integrator Circuit using Op-Amp On the other hand, there are applications where we need precisely the opposite function, called integration in calculus. The primary calculation required for the circuit is to determine the output voltage for a given input voltage for a given time. Inverting Op-amp is called Inverting because the op-amp changes the phase angle of the output signal exactly 180 degrees out of phase with respect to input signal. Integration is basically a summing process that determines the total area under the curve of a function. Wechselt die Eingangsspannung die Polarität, entlädt sich der Kondensator wieder.
