Experimenting with Diodes and Non-Linear Curve Fitting

How much does a diode's characteristics actually diviate from diode to diode? I measured a small number of diodes, and then recovered the SPICE DC parameters. Due to the limitations of my equipment, I only did this in the DC forward biased region. I'll also describe how to accurately recover the SPICE parameters using numerical methods.

Don't Throw Away your Common Sense

Just because you have a fancy computer machine, don't throw away your common sense. To find out why, just click this link: \(\sin(2 \pi x) = 0\)

If Wolfram fixes this, here's a screenshot to savor this moment:

If you don't know what's wrong, well perhaps you have already thrown away your common sense...
