Op-amp is used mostly as an integrator than a differentiator because in differentiator at high frequency, gain is high and so high-frequency noise is also amplified which absolutely abstract the differentiated signal. An op amp differentiator has R = 250 kΩ and C = 10 µ F. The input voltage is a ramp r ( t) = 12 t mV. This concept will be very easy to understand with a numerical. Both the stability and low frequency roll-off problems can be corrected by the addition of a resistor RF in the practical integrator. As we know the equation for a sine wave is Sin (2πft), but here amplitude of the signal is 5V, therefore our input signal will be 5Sin (2πft).
