Differentiator Op Amp Circuit

Differentiator circuit is application circuit from playable mathematics formula (influenced) from capacitor activity. The circuit like at picture under this with simple circuit from differentiator. To get formula differentiator, the sequence is as following: Ic = Ib + If and during value Ib = 0 hence Ic = If difference from inverting input and non-inverting input (v1 and v2) be the null and voltage amplification is very big.

At the application of differentiator circuit this op-amp there are a few changes that is addition of prisoner and capacitor which the function input signal filter to. Like seen at picture following is differentiator circuit intended. If, when input signal exceeds frequency fa hence result of output would equal to result of input, alias function of the differentiator circuit shall no longer again but as ordinary. While to drawing 226 usually applied for application integrated circuit with other application. Condition calculation value R1, C1, RF, CF is as according to condition that is:

fa

so input frequency is overcome beforehand to R1, C1 , RF, then pass to R1, C1, CF if, when the frequency exceeding fa.
