a) Consider the NMOS circuit given in Fig. 3. Assume $V_{DD}=15\mathrm{V}$. Determine the value of $R_F$ to set the current $I_R=1\mathrm{mA}$, using the transistor parameters ${\mathrm{V}}_{\mathrm{TN}}=1.2\mathrm{V},{\mathrm{K}}_{\mathrm{N}}=0.43\mathrm{mA}/{\mathrm{V}}^2$. Fig. 3. NMOS Circuit b) Add $M_O$ and $R_O$ to the circuit as given in Fig. 3 as shown in Fig. 4; to form a simple current mirror to be used as a current source. Assume $M_R$ and $M_0$ are matched with the same parameters. With $V_{DD}=15\mathrm{V}$, and the value of $R_F$ as obtained in part (a), and $R_D=5\mathrm{k}?$ determine $I_O$ and $V_{DSO}$. Fig. 4.
