Homework 3 - Solution Problem 1 (20 points): Suppose you’re trying to measure an unknown sensor resistance, Rsensor , by converting it to a voltage. For a fixed set of values of R1 , V 1 , V SS and V DD , each of the following circuits will yield an output voltage, V o , as function of Rsensor . a.b.[10 points] For each of these circuits, write the equations relating V o to R sensor . [10 points] Find the sensitivity for each of these circuits (note that the sensitivities for some of these circuits may not be constants). (a) (c)
