FET pinch off and cutoff voltage

[[email protected]]

I am wondering why the magntidue of FET cutoff voltage is the same as
the pinch off voltage ? Is there a clear explanation on this ?

There are multiple definitions, including some by manufacturers
on their datasheets, such as Vgs for Id = 250uA, etc., and they
all result in different voltages, not the same voltage.

Hello Win,

Just like in grandma's recipes. Add a "pinch" of salt. Now how much is a
pinch, really?

Hope you guys can put the waders and boats away now. Your flooding
looked worse than what we had in California a month earlier. Except that
a few hills came down, including some houses on their slopes.

Wonder how Boston and Cambridge are doing along the Charles? Most of
that "land" is reclaimed.

Here's two webcams that might help during daylight. Not much to see now.

1. Downtown looking toward the Back Bay:

2. The Boston Harbor Cam updates every five minutes during daylight
hours:

Reminds me. Ask a person not familiar with the area, "Where's Back
Bay" ?

Likewise the location of the Boston Massacre plaque always amused me.

1/32nd teaspoon comes to mind. ;-)

It's probably on www.onlineconversion.com.

I thought they filled it in in the 1800's. Isn't it under Fenway Park?

Here's some maps showing the landfill in progress:

And here's one showing where it is now:

Amuse us. Where is it?

"A simple circle of cobblestones marks the site where five American
colonists were killed by British soldiers in 1770. The brutality of
this incident helped spark the anti-British rage that ultimately led
to the American Revolution."

Kind of humbling.

Kind of inaccurate, more like.
Since "America" didn't exist as such until 1776, I think you'll
probably find that those "American colonists" were in fact British
settlers killed by their own people and consequently no good cause to
rebel against the benevolent and kindly rule of G3. This sort of
disingenuous and all-too-prevalent anti-British propaganda really gets
on my thr'pennies.

A totally misrepresented propaganda incident wherein the typical drunken
Boston low-life wharve rat trash were harassing British soldiers by
pelting them with rocks, ice, and snow balls. The British dropped them
on the spot with rifle fire, in self-defense, and after being pushed too
far. That so-called plaque is not worth taking a dump on.

And (IIRC) John Adams successfully defended the British Troops in
court.

I've heard some recent historical suggestions that the other Adams
(Sam) wrote untruths in his newspaper to incite such situations... as
in (untruthfully) saying the Brits were raping our young girls (whilst
studying their resistor tables ;-)

As a Canadian, American history is of little interest to me, so I won't get
involved in another interminable political thread.

But someone throws a snowball at you, and you drop them with rifle fire?

And that is considered self-sefense?

I guess either story has some tourism value.

I'm outta here

That's OK. The other webcam is stuck permanently on August 27, 2005, and
the two boats are still headed for a collision

The people operating the webcam are probably the same people who
certified the concrete in the "Big Dig", so they're on the lam ;-)

Except for Violet, who gave willingly.

There's at least one in every town. In my overly religious southern
community it was, naturally, the preacher's daughter ;-)

From some of the other blunders I've read, they have probably stolen a boat
and are now trying to paddle it across the Back Bay as we speak
