I have started working on a summer assignment for my Fall semester EE course and was given a gain problem with an op amp (Problem shown below - EE P3.1). My professor also gave me, what he calls, 'Typical Homework Solutions.' I have based most of my work with the example problem he gave us(Attatchment EE P3.2), but have come to a dead end in my work... 1. The problem statement, all variables and given/known data (Attatchment below - EE P3.1) Determine the transfer function of the circuit given. 2. Relevant equations Vn(t) = Vp(t) Vp(t) = Vi(t) Vn(t) = Vp(t) = Vi(t) 3. The attempt at a solution (Attatchment below - EE P3) 0 = (G1 + C1s)Vi(t) + G2[Vi(t) - Vo(t)] The thing that doesn't seem right is (looking at EE P3) that if I were to bring the Vi(t) over to the right of the equation so it is Vo(t)/Vi(t), the gain would then be ((G1 + C1s)+G2)/(G2) and that just does not seem like the correct answer.... Any ideas/input as to if I'm just wrong in thinking that is not right?
