    Hello everyone, first time posting on this site.

    I am trying to design an op amp PD controller and I have the following transfer function:

    Gc(s) = 32s + 8.

    Now from the reseach I have done it I have found that for the op amp circuit to be in the form of the image in the link below (ignore the integral op amp):


    and that its equation is the following:

    Gc(s) = RD*CD*s/(Rc*CD + 1) + RP1/RP2

    Now to determine my resistor and capcitors values I understand that I have to equate:

    Kd*s = RD*CD*s/(Rc*CD + 1)

    But I was wondering how do you do this algebraically as the equations are not in the same form.

    Any help would be appreciated as this is urgent.
