An op-amp is a “differential to single-ended” amplifier, i. A circuit in which the output voltage waveform of Op amp is the integral of the input voltage waveform is the integrator or the integrator amplifier. The follow by range of input into the R1 is Element Input and the C1 is feed back element. Describe what would happen to the output voltage if all the components were ideal. As it is a single supply it eliminates the need for a duel power supply, thus simplifying design and basic application use. If you strap a capacitor around an op-amp as a feedback in an inverting configuration, instead of a resistor, you wind up with an interesting basic circuit called an integrator. 18 6 Design and verify the operation of op – amp as an (a) adder (b) subtractor (c) integrator and (d) differentiator. One is the Differentiator and the other is Integrator and I would like to mention that these two, these two circuits were very important to early analog computers. Then, if you integrate that cosine wave, you get another 90° phase shift, producing a negative sine wave. When the voltage at P goes slightly below zero , the output of A1 will switch to negative. Below is a Multisim simulation of the integrator circuit.
