Question:

Consider the NMOS current source in Figure P10.59. Let $I_{\mathrm{REF}}=0.2 \mathrm{~mA}$, $K_{n}=0.2 \mathrm{~mA} / \mathrm{V}^{2}, V_{T N}=1 \mathrm{~V}$, and $\lambda=0.02 \mathrm{~V}^{-1}$. (All transistors are matched.) Determine the output resistance looking into the drain of $M_{6}$.
