Often, the effects of various op amp parameters on the accuracy of the circuit’s closed-loop gain are overlooked and cause an unexpected gain error both in the DC and AC domains. This article, Part 2, focuses on DC gain error, which is primarily caused by the finite DC openloop gain

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 error analysis 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 op amp gain 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. #1 Like Reply Oct 12, 2012 #2 CircuitZord Member Oct 8, 2012 59 2 That is indeed pretty convoluted to understand, are you missing some slides? It's kind of hard to figure out what's happening there. These are our lecture notes for DC imperfections in Op-Amps, it might help you a bit better. See the contents and find the DC imperfections bit. http://www.filehosting.org/file/details/383807/ELEC2133_section_2_2012.pdf #2 Like Reply Oct 12, 2012 #3 chitofan Thread Starter New Member Sep 30, 2012 15 0 Can you upload it via mediafire or send it to my email
