Why the common emmiter

[Rich Grise]

Everybody makes a mistake now and then, especially so when the
consequences are low, as in no planes will crash or anything like
that. Just say "oops" and get on with life... it's no big deal. I see
my mistakes as reminders that I should brush up on something, which
then keeps me from making the same mistake later when it really
matters, as when serious things might be involved.

Speaking of mistakes, I was in the liquor store the other day to buy
a bottle, and there was some kid at the counter. I asked, "Are you in
line?" and he sort of stepped aside and said "go ahead". So I got my
bottle, handed the proprietor two fives, he rang it up, put it in the
register, and asked for another $1.77 or something. I was confused -
"What? You can't make change out of the till?" And some minor discussion
ensued, and the guy realized that I had given him two fives, not a five
and a one, and he was just mortified - "Oh, I make mistake! So sorry!"

I said, "Oh, a mistake. No big deal, everybody makes mistakes - that's
how we learn stuff. " The guy counted out the correct change, and
all was well.

On the way out the door, the kid that had been standing watching the
whole transaction said, "Yeah, I learned something here too."

It made me feel good.

Cheers!
Rich

You write awfully well for being dyslexic.

My oldest posts (before my emailer had spell checking) were
a mess. I still can't seem to write the word "to" as
anything but "ot" and have to go back and correct it most of
the time. It was in my spell checker (I assume as an
acronym for off topic or old testament or something), but I
managed to delete ot from the dictionary, so the spell
checker now catches those. I can read something I am
composing, and it looks fine, but as soon as I see it in a
reply or in, Google, all the errors jump out at me. I used
to get pissed about writing so poorly, but it didn't help,
so I gave it up.

When I was trained as a cashier (at age 15) I was taught to
always lay the tendered money on the shelf above the cash
drawer, till the customer had accepted his change and left.
Then to put it in the drawer, close it and serve the next
customer.

That way, if there was a question about what was given, the
dispute was easily settled. My employer was not so much
worried about my mistakes but with people intentionally
scamming me by claiming they had given me a big bill and
were short changed. A couple times people didn't notice
where I put their money and started protesting loudly about
being short changed, but quickly bowed out when I picked up
their payment and showed it to them. Sadly, it seems that
such practices and how to count out change are becoming a
lost art.

I have a few words I often mis-type. "Status" is one, and "the"
sometimes comes out "teh."

status status stayst status stayus

see?

Yup. And he writes awfully well, period.

I do and see that a lot.

For a few years, I could not type 'ratio' without it coming
out 'ration', automatically. I finally got tired of missing
it (the spell checker is no help) and now every time (well,
almost every time) I type 'ratio', I slow down and force
myself to leave the 'n' off. But the fingers always put up
an argument. "t-i-o is always followed by n, dammit."

A lot of my typing errors are homonyms. Weird.

Not that I can type... I'm still a two-finger, gotta-see-the-keyboard
typer. That's probably why I'm a pretty good programmer... I type slow
enough to think about what I'm doing.

I always draw the emitters up on PNPs and the emitters down on NPN's.
Voltages are more positive at the top of the sheet, and current flows
down.

I draw mosfsts sort of like IGBTs...

See? Can't spell!

Gee, John. No one is perfect. If you were someone would want to
nail you to a cross.

Just look at the transistor symbol. Obviously the emitter is heavier,
so it settles down to ground.

But I'm still confused about PNP's. I figure the emitters must be
helium implanted, since they tend to go up.

Of course nobody lives there permanently. However, the scientists in
Antarctica do need to account for the transistors in their equipment
running in "inverted down-under" mode. If transistor-inversion were
not accounted for properly in their data analysis, then we'd all be
hearing reports (erroneously) of the south pole's ozone **surplus**.

Thankfully, we are smart enough to know better.

Don't be silly. The scientists are smart enough to turn their
equipment upside down so it works, just like it does in the real world.

hello every body, i have a quistion. Why do we use the common emmiter ?

Does anybody remember the dual emitter transistor? You could have
common emitter-emitter, or common emitter and common base at the same
time.

I only remeber the dual gate fet that had a wire ring around all the
leads that you removed after the fet was installed. And if you wanted
to remove the fet from the circuit you needed to wrap some wire around
the leads to avoid static. But it never worked since the wire would
come loose and the thing was always dead when I got it back in the
circuit.

You give them too much credit. It was one of their technicians who
said to them, "Hey! We can turn the equipment upside down so it
works, just like it does in the real world!"

LOL

Do you always have to state the obvious?

When was the last time a research team admitted, "While we were
sleeping off three weeks of heavy drinking, one of our lowly techs
figured everything out. The theory, and the required equipment to prove
the theory. He then designed and built the required device and wrote the
documentation. After we saw that it worked, we shot him and dumped his
body down an abandoned well so the truth would never come out."
