How do you use operational amplifier as differentiator and adder/subtractor.
Fig. shows differentiator or differentiation amplifier. As its name implies, circuit performs mathematical operation of differentiation; that is, output waveform is derivative of the input waveform. Differentiator can be constructed from a basic inverting amplifier, if an input resistor R1 is replaced by a capacitor C1.
Expression for the output voltage can be obtained from Kirchoff's current equation written at node v2 as follows:
