I am having trouble (I think) coming up with the proper transfer function for the following circuit:

I do a KCL equation at node A and also at the negative terminal of the op amp.

I come up with the following transfer function...

Vo/Vi = (-s^2*R1R2C1C2)/(s*(R1C1+R1C2+R2C2)+1)

When I model the circuit in Spice, it looks like an RLC circuit, however I can't seem to get a transfer function in the proper form (with an obvious damping factor and resonant frequency).

Is my transfer function wrong?

I hope this wasn't too confusing. Help!
