When a comparator is used to compare a signal amplitude to a fixed d.c. level (reference voltage), the circuit is known as a level detector. Differentiation amplifier produces a) Output waveform as integration of input waveform b) Input waveform as integration of output waveform c) Output waveform as derivative of input waveform To find out the output voltage, we integrate both sides of the above equation to get. The differentiator circuit is essentially a high-pass filter. differentiation means difference -division or integration means product sum so here division reverse product (multiplication) difference reverse sum so we can write differentiation = dy/dx or integration = ⨜ydx hence these two are reverse process of each other in physics we use both wherever application required . Op-amp Differentiator is an electronic circuit that produces output that is proportional to the differentiation of the applied input. The faster the input voltage changes, the larger the magnitude of the output voltage. Basically it performs mathematical operation of differentiation. Since the gain of a comparator is equal to AOL , virtually any difference voltage at the inputs will cause the output to go to one of the saturation stage and stay there until the voltage difference is removed. That means, a differentiator produces an output voltage that is proportional to the rate of change of the input voltage. Fig.6 shows the action of a comparator.
