Design a bias reference as shown in the provided circuit image to produce $100 \mu \mathrm{~A}$ output current. Assume that for $T_1, I_S=10^{-14} \mathrm{~A}$. Assume that $\partial V_{B E} / \partial T=-2 \mathrm{mV} /{ }^{\circ} \mathrm{C}$ and that $(1 / R)(\partial R / \partial T)=+1500 \mathrm{ppm} /{ }^{\circ} \mathrm{C}$.
