I was given a pretty intuitive explanation of BJT
forward operation in my semiconductor courses
which was charge based. But evidently most people
prefer to think about voltage control. Not sure why;
thinking in terms of current generally works out
for me in analog IC design. Other than bandgaps,
where you do care about particular base-emitter
voltages, but even there it's voltage at ratioed
current densities and you take what you get.
There's a religiosity about it that disinclines me to
bother trying to explain it to people who don't
really need it.
