Figure 1: An NMOS current mirror (a) without and (b) with a cascode transistor. Do the following for both current mirrors in Figure 1 . 1. Perform a hand analysis to find the expression of the small-signal gain. 2. Perform a hand analysis to find the numerical value of the output impedance. Do not expect good matching between hand calculation and simulation as the output resistance of the actual transistor and thus, the model depends on Vos. This effect is not captured by the square law you use in hand analysis. - Use \( l_{D 1}=1 \mathrm{~mA} \) and \( V_{D D}=5 \mathrm{~V} \). - For the cascoded current mirror, set \( \mathrm{vaz}^{2} \) in a way to maximize the output swing while keeping the transistors in saturation.
