Integration Circuit Amplifier

Integration is obtained by reversing the resistor and the capacitor as shown in figure below.

 

 

The capacitor is now in the feedback loop.

Analysis gives

 

or

 

 

Using dV/dt=I/C gives

 

and thus the same result as above.

 

The frequency response is shown in figure below

We can combine the above inverting, summing, offset, differentiation and integration circuits to build an analog computer that can solve differential equations. However, today, the differentiators and integrators are mainly used to condition signals.
