a) describes the impact of non--ideal op amp characteristics on the output of the inverting amplifier circuit. Assume that Rs = 10k and Rf = 1 M. Let A = 105, Ri = 2 M, R0 = 75 . If these nominal non--ideal parameters are replaced, one at a time, by A = 50000, Ri = 1 M and R0 = 150 (each of which is twice as bad as the nominal values), which parameter has the largest impact on the output voltage? In other words, the output voltage is most sensitive to the variation of which non--ideal parameter?
b) Compare the above results with the possibility that Rf is chosen to an accuracy of 1%. Which has a bigger impact on the output voltage?
