Thanks for giving me the guideline.

Redo this question I try to redo this question by using the nodal analysis : I label my diagram in detail which is attached to this post. The following is my step to solve for Vout. Vx= 72mV At Node'A': Ix + Iy - Iz = 0 (Vx-Va/12k) + (Vout - Va /84k) - (Va - Vb/4k) = 0...

For the Gain = Vout/Vin = 1 + (Rf+Rs) = 1 + (100/20) = 6 This is my analysis from the circuit. Sorry that I make mistakes for the equation, should be Rf = 100K ohms , while Rs = 20k ohms Vx = (5/4+5) Vin = 5/9 Vin The bias current of the positive input of the op amp is 0, so the 4k ohms and...

Homework Statement Consider the circuit that attaches in the attachment. Calculate the Vout. Homework Equations Non-inverting om amp: Gain = Vout/Vin = 1 + (Rf+Rs) Golden Rules: i- = i+ =0 V- = V+ The Attempt at a Solution Gain = Vout/Vin = 1 + (Rf+Rs)...
