Hi guys, I have a winter break homework assignment for my EE college course. I've been given what seems to be a simple circuit analysis problem, but feel that I am making it much harder on my self by using nodal analysis. I have to find the transfer function of the circuit. My work has been scanned and attached, any input as to whether I am on the right or wrong track would be greatly appreciated.
Determine the transfer function, Av(s)=Vo(s)/Vi(s), in terms of s, R1, R2, R3, C1, and C2.
Assumptions:
ALF should be equal to (R3)/(R3+RZ) because the caps open at low frequencies.
RZ is R1 and R2 in parallel.
