Well- it's not called the "half circuit" concept, it's called breaking
the total analysis into common- and differential- mode computation.

when this stuff was invented

Yup. Stroger Switches were invented in 1884--by an undertaker.

Do you think they used -48V back then?

It was less standardized. Short loops were as little as -12V, long
loops could be more than -48V. It depended on who was selling the
switch and equipment too.

Large parts of the civilized world use -24V as the default
on telco loops.

In Sweden -48V for POTS, and -96V for ISDN.

Hi Nicholas,

It's not the ears they are after ... can't make a dollar bill from
a pig's ear.

Actually you can. Maybe not a Dollar, but at least about half that minus
processing and other costs. Just ask our dogs, they love them. Pig ears
sell for around $12 per 25-pack at the wholesale store ;-)

Too bad that in that whole big rant they don't even have a link to this
alleged "report." They'd have a lot more credibility, although zero times
anything is still zero, but if they said, "Here's the report the black
copters are repressing:" and gone on with some report that said, "such and
such a field was treated, and it was found that..."

Know what I mean?

Thanks,

He also calls beta a "figure of merit", like I suggested.

Beta can be increased reducing the transistor's base thickness,
which in turn reduces the Early voltage. Remember Bob Widlar's
super-beta transistors? The figure of merit is the product of
beta and Early voltage. The product is a constant for a given
Fab transistor process - it's a tradeoff. Is that what he says?

You were going to post a link to this, "Modeling the Bipolar
Transistor," by Ian Getreu (when he was working at Tektronix and
probably with their STS (semiconductor test systems) group when
it still existed.)" Right?

There you and a bunch of other long winded ignorant people go with your
hysterical misunderstanding of the system. All of this regulation has to
do with ultimately enforcing much more onerous registration requirements
on every single entity in the world, foreign or domestic, that have
anything to do with *bulk* food distribution within the US. The prior
notice requirement on individual mailings for non-personal use such as
your case have to do with *traceability* to a much larger problem with a
registered manufacturer, processor, distributor, agent, etc... in the
event a problem does develop with contamination, accidental or
deliberate, of the product you mailed. It has nothing to do with
preventing a terrorist from mailing a single package, but it does have
everything to do with quickly tracing back to a larger scale terrorist
sabotage of the food product supply chain unwittingly introduced into
the US by an individual mailer. This is all about statistical risk
management and damage mitigation- it is NOT about setting up an
impenetrable barrier to attack, which is not practical. The alternative
is refusal of the shipment at the port of entry- take your pick.

DHS is very interested in analyzing statistical data patterns to
identify bio-terrorist attacks. We (Pacific Northwest National
Laboratory) have a sizeable project with DHS to analyze purchase
patterns from - guess who? - WalMart. The idea is that if there is a
bio attack one of the first indicators will be people purchasing
over-the-counter meds. The type of meds will point back to symptoms,
which point back to the nature of the attack.

No, I didn't mean a single transistor.

Just to show you the limitations that the
Gain = gm Vbe model has ... here goes.
Look at my original equation for a single transistor.

With no signal Ic1 = Is exp( Vbe/Vt)

I'd write: Ie_quiescent = Is*exp(Vbe_quiescent/[kT/q]-1)

With a signal Ic2 = Is exp( Vbe + Vsignal)/Vt

I'd write: Ie(t) = Is*exp([Vbe_quiescent+V(t)]/[Kt/q]-1)

In which case

Ie(t) = IB.exp(V(t)/Kt/q)

Ignoring the 1, with IB=Is.exp(Vbe_quiescent/Vt)

Thanks, I was typing but I sure wasn't watching myself there. I should have
read it twice!! Thanks for the kick.

= Ic1 exp Vsignal/Vt = Ic1[1 + Vsignal/Vt + 1/2 * (Vsignal/Vt)^2 +
...) which is a binomial expansion of exp Vsignal/Vt
snip

Binomial expansion?? Here's where we break company on several
fronts. First, I've no idea why you apply a binomial expansion or
how you derive your terms, here.

A binomial expansion is incorrect. The binomial expansion is an
expansion of say, (1+x)^n

Completely agreed. I had no idea where he was going with it.

Maybe I'm just being stubborn,
though. Do you mean a Taylor's expansion about the point at
x=Vbe_quiescent?

Probably.

Perhaps, but I still don't know how he feels it all bears on the 2-NPN
differential amp. Have to wait and see, I suppose.

Just east of there is a huge (100 sq miles or so.) California sytle
agro-industrial farm growing just about anything. A lot of fruit
orchards, potoato fields, an a lot of signs saying Private Property
don't come here.

"potoato" is that a new veggy? East is dry land wheat farming.
Immediately E, NE and N is the Columbia Basin Irrigation District.

I drove the highway from Waitsburg to Pasco (Touchet Valley) about a
dozen years ago. Just East of Pasco, but South of the Snake, is a really
big spread. 60,000 acres, as I vaguely remember some mention of it in
the newspaper, (might have only been 35,000 acres ;-)). They built
their own irrigation system, some time in the late '70s or mid '80s,
judging from the size of the fruit trees. They had signs at each
"building installation", (more of a motor pool than a barn, and there
were several of them on the highway) that translated to "don't bother
to stop here if you need help, nobody lives here, private property".
Not your typical family farm.
