Question:

The cut-in voltage of the diode shown in the circuit in Figure P1.46 is $V_{\gamma}=0.7 \mathrm{~V}$. The diode is to remain biased "on" for a power supply voltage in the range $5 \leq V_{P S} \leq 10 \mathrm{~V}$. The minimum diode current is to be $I_{D}(\mathrm{~min})=2 \mathrm{~mA}$. The maximum power dissipated in the diode is to be no more than $10 \mathrm{~mW}$. Determine appropriate values of $R_{1}$ and $R_{2}$.
