Figure 5.3.1
The MOSFET in Fig. 5.3.1 has $V_{t}=0.5 \mathrm{~V}, k_{n}^{\prime}=$ $0.4 \mathrm{~mA} / \mathrm{V}^{2}, V_{A}=10 \mathrm{~V}$ , and $W / L=10$ . Find the value of $R_{D}$ that results in
i. $V_{D}=0.1 \mathrm{~V}$
ii. $V_{D}=1.5 \mathrm{~V}$
In each case, find $I_{D}$ and the incremental drain-tosource resistance of the MOSFET.
