I am having difficulty understanding my lecture notes as the workings are extremely convoluted.
How was the Vout equation derived? Using nodal analysis, we can get (Vout - V-)/R2 = (V- - Vground)/R1 but the equation in the 3rd picture doesn't correspond to anything i know or can understand.
Also, at the node between R1 and R2, shouldn't the voltage should be (Ios/2-Ib)(Rx+1k)?
There shouldn't be any mistakes because the lecturer did an alternative analysis using superposition theorem to get the same result, but i would like to understand how she derived the workings as well (i would ask her, but i already have appointments scheduled and i don't want to fall behind in my studies)
Please help!
P.S. if anybody knows a good reference for analyzing op amp choices while factoring just Vos and Ib, i would love to know it. I've hunted high and low for such materials and came up short.
