i am having quite a difficulty to express the output voltage of the 2nd opamp, the purpose of the 33k, 10 k resistor. Even if the input is only a fixed dc value why is that i get triangular pulses at the end of the second opamp?
IS this circuit a practical one? every time i had try to use a differentiator in a practical circuit it does not work.
