Question

An operational amplifier (op-amp) integrator is an operational amplifier circuit that performs the mathematical operation of integration with respect to time—this means the output voltage is proportional to the input voltage integrated over time.

A differentiator is an op amp-based circuit, whose output signal is proportional to the differentiation of the input signal. An op-amp differentiator is basically an inverting amplifier with a capacitor of suitable value at its input terminal. The electric potential of inverting terminal is also zero, as the opamp is ideal.
