Basically what you say is right, but I have to correct you on this small
nit: =A0Proportional *IS* linear.

An Ohmic resistance is linear but semiconductor behavior is often
exponential or logarithmic. A good example is the drop across a diode:

Scroll down to the part about kT/q.
The effect is that the voltage drop rises with the logarithm of the
current.

This one shows how the forward drop changes inversely with
temperatu

Yep, quite true.... I've also had ordinary diodes
"go zener" instead of behaving.

But Leo seems to think proportional == linearly proportional.
I disagree but decided it wasn't worth arguing about.
