Revisit the exact analysis of the inverting amplifier in Section 4.3.
(a) Find an expression for the voltage gain if R in , R out = 0, and A o .
(b) For R 2 = 27 k and R 1 = 3 k , plot the ratio of the actual gain to the ideal gain for A o = 1000 and 1 k R in 100 k .
(c) From your plot, does the ratio approach unity as R in increases or decreases
(d) From your plot in (b), what is the minimum value of R in if the gain ratio is to be at least 0.98
