Good thing he published it for free then, isn't it? It's all in the white papers...and here.
I find it easier to just go ahead and build something than to obsess over arcane details. For instance, all the theory, PSPICE, and book learning in the world won't prepare you for that IRF P-ch glitch. It's just kinda there. The only way you're going to find out about things is to go ahead and bump your nose into them.

bump your nose...
...and I've got the band-aids.
I just want some basic info located in one easy to access location. That's all. Nothing fancy.
Just show me how to manipulate the formulas, just like they do in my electronics publications. If everything's the same, then I'll be all the wiser. But, if there's a different way to handle FETs, then I'd like to know that too.
There's something about reading simple black and white.
I'm going to find a MOSFET publication. I just thought this forum would be more entertaining.

carpenter,

There is way to collect such knowledge already present in different topics
and put it into one
STICKY: The MOSFET Glossary, Guidelines and Formulas
like we did it in another forum!
The Gainclone Glossary
is a good collection of knowledge in the topic of Gainclone Building.
It is in the form a glossary, dictionary.
Gainclone words, terms used and expressions, From A to Z.
This glossary was suggested by another member as a good help for first timers
to get into the jargon and quickly learn the basics about gainclone building.
On my suggestion, to avoid anyone to put anything, not 100% suitable or Off topic, into this glossary,
we made one open glossary development thread
and at same time made The Gainclone Glossary (Main Thread) Closed.
A couple of members with good general Gainclone knowledge and the forum owner ( Gregg Baker, I think his name is )
are the only one to edit and add new material into this topic.

If we at www.diyaudio.com want to collect good rules / guidelines for MOSFET design
from this forum and put it into one topic
this could easily be done the same way.
There are plenty of such stuff, for sure!, by Nelson Pass, GRollins and many many other members with such valuable knowhow,
that has been posted into different projects/topics over the years!
###########
As mentioned, this way needs the cooperation of moderators
and possibly one or two other guys with good general MOSFET-knowledge ( maybe carpenter as he is really motivated for it ).
These will be given edit/post right in this topic:
The MOSFET Glossary, Guidelines and Formulas - STICKY and Closed
And they will, when they have some spare time, have a look at suggested stuff/contributions and copy good stuff from
MOSFET Glossary, Guidelines and Formulas ( development thread ) - Open for posters
into main thread.

Gainclone.com with The Gainclone Glossary

Hi Car,
re post26 & 27.
your formulae are correct (at DC or low frequency).
Plug these into a spreadsheet to make the sums easy to manipulate.
You could plot a graph between the unknown Vgs and Is for various Vgs.
Tthen extract values from the datasheet to find the approximate current your circuit will flow D to S.
Then set up a little experiment to see if it matches the model.

in the spirit of the starting post of this thread, a good intro to depletion mode MOSFETs can be found in this EDN article
