The input signal to the differentiator is applied to the capacitor. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time. Offers advantages in performance, power consumption, and cost savings and also addresses many difficult application challenges found in traditional in-amps. Note that the transistor current source is inside the feedback loop. The current is determined by the formula: Current Out = (V+ - Vref) / R2. The integral of a square wave is a triangular wave, as you can see. One of them is to make the integrator integrator circuit functions to produce an output voltage which is an integral function of time from the input voltage. It is possible the fast spikes when the 555 switches are caused by poor decoupling (you may look at power rails with the scope) or simply it is an artifact on your scope. A circuit in which output voltage waveform is the time integral of the input voltage waveform is called integrator or integrating amplifier.
