Applications of Op-amp Differentiator. Differentiation has applications to nearly all quantitative disciplines. According to the virtual short concept, the voltage at the inverting input terminal of opamp will be equal to the voltage present at its non-inverting input terminal. A feedback resistor is then used to provide the negative feedback around the op amp chip - this is connected from the output of the operational amplifier to its inverting input. Since the op-amp is ideal and negative feedback is present, the voltage of the inverting terminal (V−) is equal to the voltage of the non-inverting terminal (V+ = 0V), according to the virtual short concept.
