Opamp Circuit Analysis

1. The problem statement, all variables and given/known data

Find the voltage gain, V0/Vs, for the circuit below. All resistors are in Ohms.









2. Relevant equations

I identified this as a non inverting amplifier. Therefore:

[tex]

V_{0}=\frac{R_{S}+ R_{f}}{R_{s}}V_g

[/tex]



3. The attempt at a solution





Vo = 8/3*V1 (v1 = output of U1)

V1 = 29/900*vs



V0 = 58/675*Vs





This does not agree with LT Spice. I am not sure how to break this apart to analyze it.
