What is a differential amplifier and how does it work?

An op-amp differentiator or a differentiator amplifier is a circuit configuration that is inverse of the integrator circuit. It produces an output signal where the instantaneous amplitude is proportional to the rate of change of the applied input voltage.
Differential amplifiers are used mainly to suppress noise. Noise is generated in the wires and cables, due to electromagnetic induction, etc., and it causes a difference in potential (i.e., noise) between the signal source ground and the circuit ground.
