Diode modeling in verilog a

[ouij]

Hello,

I am modeling a diode using verilog ams but I have a problem when I simulate its behaviour in different temperatures.

The simple equation of the diode (Id=IS∗(eVd/Vt−1)) is not enough because it gives me the inverse of the predicted results.

Could you help me to find a way to simulate the temperature dependency correctly?

Reflect temperature dependency for Is.

yes i found that Is changes whith temperature following this equation :IS(T)=IS∗(T/T0)XTI/N∗exp((T0−1)∗EGVt)
Do you have any idea if i have to add this equation on my model or what should I do exactly?

Your expression is easy zero memory, so simply write it.

I can not understand what you are embarassing at all, sincce it is too easy.

I don't know what simulator you use.
But examples are available in any simulator.
