### 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...
