The I-V characteristics of the diode D in the circuit below is given by \(I = I_s \left( e^{\frac{qV}{k_B T}} -1 \right) \), where Is is the reverse saturation current, V is the voltage across the diode and T is the absolute temperature.
If the input voltage is Vin, then the output voltage Vout is?
1
\(\frac{k_B T}{q} \ln \left( \frac{q (-V_{in} + I_s R)}{k_B T} \right) \)
2
\(I_s R \ln \left( \frac{qV_{in}}{k_B T} + 1 \right ) \)
3
\(\frac{k_B T}{q} \ln \left( \frac{q (V_{in} + I_s R)}{k_B T} \right) \)
