Kevin, your drawing renders poorly on computer screens,
and needs work. Perhaps a gif file (always better than
jpg for drawings), or an Acrobat vectorized version?

I'll see what I can do. I could post the SS file to my site.

Wait untill they hear me speak. I'm from London, mate.

I read somewhere that a London cab driver with an 8th grade education
can typically (at least initially) pass for a highly educated
professional in the US, based on the accent alone. The last London
cabbie I had sported an Italian-English accent, however.


Best regards,

You are truly dumb as a stump... I think you have trumped Burridge for

Oh how imaginative ... Another one in the category of Kaylward and
Activex. Sorry for being too advanced for you ...

I love to cook with wine. Sometimes I even put it in the food.

You should use oil instead of wine ... it certainly will accelerate
your death .. but hey you might be less imbecilic and will fart less
LOL.

Don't take the bait Kevin. Having lost on transistors, people want to
beat you on grammar. If I were you I'd settle for being an electronics
engineer and let them be expert grammatical engineers.

Remember, that CCCS is incredibly inadequate, which you didn't address
(because I am correct.) It isn't that Beta isn't useful, but it is
an incredibly narrow view of transistor action. (The CCCS Beta model
is just silly.)

Again, CCCS is incredibly inadequate, but the various voltage controlled
models work great.

Of course, the actual internal transistor action comes much closer to
a field model (which is voltage controlled.)

Anything else (trying to justify CCCS by noting the mention of Beta)
tends to show incompetence or troll.

Your just trolling, now go away.

Kevin Aylward

Hey, Kev, Please try to use good English... you consistently use
"your" when it should be "you're" ;-)


Oh, does your and you're sound any different?

Yes, they actually do, if you're sensitive to nuances. But the point
is that USENET is a written medium, and the insistence on using
incorrect spelling, punctuation, grammar, and syntax marks one as an
illiterate.


Only for those who are too illiterate to understand what "illiterate"
actually means.

It takes way more errors than a few trivial mistakes to make someone
illiterate. Why don't you check up in the dictionary, if your not
sure of the meaning?

Put the 're in where you wish.



You destroy your own credibility by not bothering to check the
difference, and compound the error, and show irascible
blockheadedness by insisting that it doesn't make any difference.


It doesn't. Anyone who don't understand the true meaning is too
illiterate to care about.



But you never listen or take advice, so I might as well be trying to
teach a brick to fly.



I saw a giant pig fly once at a Pink Floyed concert.

Kevin Aylward

Oh, I thought it was a hallucination.


I must admit that could have been a real possibility, for obvious
concert going reasons.

Snort. LOL.

The concert in Auckland, New Zealand was kinda interesting. I came home
from work to find 20 or so strangers at my house, one of whom (Penny)
gave me a large slice of green cake (that tasted suspiciously like
compost) so all was well. Many substances were consumed, as I lived
about 20mins walk from Western Springs Stadium - although staggering
that far took a good 45 mins. Penny passed out outside the venue so we
left her there, and didnt see her for 2 days - she had never been to
auckland and got lost, only to find her way to the cop shop 2 days
later, where we then found her.

During the concert I was dreadfully hungry, but only had hash cake to
eat - ultimately that was not a solution, so after the concert we went
to the Uncles burger bar on K'Rd. The queue was about 200 people, and it
took 2.5 hours to get my hamburger but that was OK.

All the yes/no posts have simply been talking at cross-purposes, based
on differing interpretations of the question. Besides, are you trying to
claim semiconductor physics as your great idea?

And when you get right down to it, nobody can answer the question "what
IS a transistor" because we dont know what an electron really *IS* (or a
subatomic particle, gravity etc). But who gives a shit - beta and/or gm
work well enough for me, so I use them where appropriate, along with any
other tools I find useful, without the slightest concern as to whats
really going on.

Not me. I design electronics.

Exactly. There's a heirarchy of models, from simple diode+beta all the
way through Maxwell and quantum mechanics. One would have to be, as
they say, daft to pick and use a model that's more complex than the
situation justifies, or one that is too simple to be realistic.

I bet that the guys who sneer at beta as "for beginners and bench
techs" secretly use a simple beta model in the privacy of their own
bedrooms when the drive is 5-volt CMOS through a 1K resistor.

I bet you're right, too. Hell, give me a model based on nano-scale
dancing chickens that adequately predicts semiconductor behaviour in the
regions of interest to me, and I'll use it (if there isn't a better way)

Emotions exist, so whats your problem?



Ahmm... my "stand back" = your "be"

No, "be" the one who's standing back, but also "be" the one who is feeling
the feeling. Observe the duality within yourself, but let the feeling
simply flow, like "current." ;-)

It's really that simple.
Feelings may or not tell you about reality.

If not reality, then what do they tell you about?
Emotions are certainly the
only way we can experience any reality, but such emotions do not
necessarily relate to reality, and there is no way to prove which is
which.

"Prove" to whose satisfaction? If I hit my thumb with a hammer, it hurts.
I feel it. To whom do I need to prove that? When I accidentally ran over a
chipmunk and felt its little head crush under my wheel, I wept. Do I need
to "prove" anything to anybody?

No.

Descartes thinks that he exists.

I _know_, because I can _feel_ it.

Cheers!
Rich
