In its basic form the centre of the circuit is based around the operational amplifier itself. This means that a fast change to the input voltage signal, the greater the output voltage change in response. 13 V . Op-Amp differentiator performs a derivative operation on input voltage and gives its result as output voltage. The result of this is that the output signal is in-phase with the input signal. If it changes fast enough, the output will track it almost exactly, and then decay to smaller values: Oh wait. Let A and B are the two inputs of the OR gate and output stable.

The addition of resistor R 1 and capacitor C f stabilizes the circuit at higher frequencies, and also reduces the effect of noise on the circuit. When input is a square wave: When the input fed to an integrating circuit is a square wave, the output will be a triangular wave as shown in fig.5. Using this relationship the output voltage as a result of an actual applied input wave function was determined, where the input voltage was a sinusoidal function of amplitude A and frequency w/(2pi). An op-amp integrating circuit produces an output voltage which is proportional to the area (amplitude multiplied by time) contained under the waveform. That means, a differentiator produces an output voltage that is proportional to the rate of change of the input voltage. With an ideal amplifier we can just multiply the gain with the input voltage. Determine the output voltage of an op-amp for input voltage of 200 uV and 160 uV. Assume the input voltage changes at constant rate.
