Consider the diode circuit shown below. The diode, D, obeys the current-voltage characteristic $I_{D}=I_{S}\left ( exp\left ( \dfrac{V_{D}}{nV_{T}} \right )-1 \right )$, where $n> 1, V_{T}> 0, V_{D}$ is the voltage across the diode and $I_{D}$ is the current through it. The circuit is biased so that voltage, $V> 0$ and current, $I<0$. If you had to design this circuit to transfer maximum power from the current source $\left ( I_{1} \right )$ to a resistive load (not shown) at the output, what values of $R_{1}\:and\:R_{2}$ would you choose?

  1. Large $R_{1}$ and large $R_{2}$.
  2. Small $R_{1}$ and small $R_{2}$.
  3. Large $R_{1}$ and small $R_{2}$.
  4. Small $R_{1}$ and large $R_{2}$.
