A certain P-N junction diode of germanium has a leakage current of 10^-8 A at 127 Deg C. The diode is forward-biased with a constant-current source of 1 mA at room temperature. If current is assumed to remain constant calculate the junction barrier voltage at 127 Deg C.

- There is the room temperature and 127 Deg C. Not sure if u have to use the room temperature as well somehow?!


P.S. This was posted in a previous thread but wasn't resolved, hope someone else can have a go.

Use the diode equation and rearrange it to find V. Use 127 degrees Celcious to define KT (note that you have to convert celcious to kelvin).
