Homework Statement
I am trying to derive the transfer function for the circuit (figure 6). I have what the final transfer function is supposed to be (figure 7) but I can't derive it.
Homework Equations
((v2+) - 12)/12k + (v2+)/12k + ((v2+) - v1)/c2= 0
(v2-)/c1 + ((v2-) - Vout)/15k = 0
v1=A(v2+ - v2-)
The Attempt at a Solution
I have gotten up to the point in figure 9 but then i am stuck. Any help would be appreciated.
