Objective: Compare the output resistance of the cascode MOSFET current source to that of the two-transistor current source.
Consider the two-transistor current source in Figure 10.17 and the cascode current source in Figure 10.18. Assume I_{REF} = I_{O} = 100 µA in both circuits, λ = 0.01 V^{−1} for all transistors, and g_{m} = 0.5 mA/V.
