The circuit at right integrates the input voltage <math>V_{in}</math> by using an Amplifier. |
|||
<math>V_{out} = \frac{-1}{R_{1}*C}\int V_{in} dt |
|||
</math> |
|||
"<math>R_{2}</math> ; Provides negative feedback for low output impedance needs. But it also distorts the output."<sup>1</sup> |
|||
The use of an Integrator circuit is the opposite of a Differentiator circuit. In other words, If you have a "^^^" style input and you Differentiate it you will get a "square sine wave" output. If you run the "square sine wave" as the input to an Integrator circuit you will end up with the "^^^" for the output. |
|||
The Resistor (<math>R_{2}</math>) Is used to provide feedback of the output DC voltage. Without this, circuit wouldn't perform as calculated because of the un-ideal conditions of real life. |
