Consider the diode circuit shown below. The diode, D, obeys the current-voltage characteristic \({I_D} = {I_S}\left( {\exp \left( {\frac{{{V_D}}}{{n{V_T}\;}}} \right) - 1} \right)\), where n > 1, VT > 0, VD is the voltage across the diode and ID 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 (I1) to a resistive load (not shown) at the output, what values of R1 and R2 would you choose?

• A. Large R1 and large R2
• B. Small R1 and small R2
• C. Large R1 and small R2
• D. Small R1 and large R2
