By introducing electrical reactance into the feedback loops of op-amp amplifier circuits, we can cause the output to respond to changes in Drawing their names from their respective calculus functions, the integrator produces a voltage output proportional to the product (multiplication) of the input voltage and time;

The integrator basically works like this: whatever current I you get flowing in R1, gets integrated across capacitor C1. The output voltage Vo is simply the voltage across C1. One great application of the integrator is generating a ramp voltage.

When , the integrator works as an open loop amplifier. This is because the capacitor CF acts as an open circuit to the input offset voltage . This input offset voltage and the part of the input current charging capacitor CF produce the error voltage at the output of the integrator.

If the input is a constant positive dc voltage, the output will be a negative linear ramp. There is no exponential factor in an op amp integrator. The equation for the ramp will be Vout = -Vint/RC, where t is time in seconds.

How do We Build an Op-amp RC Integrator? ... Building op-amp integrator (go to Step 3) ... Finally, remove all the "unnecessary" components of the picture (voltage bars, current loops, power supplies etc.) and you will get the classic circuit diagram of the op-amp integrator. It will be simple, small, easy remembering but...
