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.
