Diode Model

Question asked by rfdude on Dec 14, 2010

I'm trying to characterise a diode and transfer the values to a model in ADS. I am using the "Diode_Model" and entered the saturation current, the emission coefficient and the temperature. The help of ADS says that these 3 values determine the DC behaviour of the diode.
But the resulting values differ a little from what you get when you enter the parameters in the "normal" diode formula.


The attached image shows the two curves. [Edit: As the attachment doesn't work have a look at] Which parameters do i have to adjust to make the two curves congruent?

Thanks a lot for your time.
