A current-to-voltage converter is shown in Figure P9.54. The current source has a finite output resistance RS , and the op-amp has a finite open-loop differential gain Aod (a) Show that the input resistance is given by

(b) If RF = 10 kΩ and Aod = 1000, determine the range of RS such that the output voltage deviates from its ideal value by less than 1 percent.
