(42S) Shockley Diode Equation (solver program)

[Luigi Vampa]

Solver program of the current vs. voltage of a p-n junction diode (Shockley Equation)
ID: diode current (Amps).
IS: saturation current (Amps). 1e-9 for Silicon.
VD: diode voltage (Volts).
N: quality factor (n=1 ideal diode, 1<n<2 real diodes).
T: temperature (Kelvin).
