It is required to design the circuit of the provided circuit image to establish a dc drain curtent $I_D=0.5 \mathrm{~mA}$. The MOSFET is specified to have $V_t=1 \mathrm{~V}$ and $k_n^{\prime} W / L=1 \mathrm{~mA} / \mathrm{V}^2$. For simplicity, neglect the channel-length modulation clfect (i.e., assume $\lambda=0$ ). Use a power-supply $V_{D D}=15 \mathrm{~V}$.
