more whining

Oooops! My apologies, I read "ka" as a capacitor, not as a diode... I hate ASCII schematics ;-)

Hello John,

I used to read EE Times a bit, often their German edition. Then they let some guys go and the whole thing became EDA heavy. That's about as interesting as reading an essay about adjustable wrenches.

Using ULN (Universal Larkin Notation) that would have been...

which is, agreed, a whole nother kettle of fish. But it has interesting behavior, too, sort of like the uni-shot circuit... just cascade a chain of these.

Hello Jim,

A kapacitor? Like in Krispy Creme doughnuts?

Maybe we should suggest the ASCII convention of using "co" for condenser :-)

Sortently ;-)

It finds the peak, since the capacitor charges toward VP-vBE.

EE Times is OK, for the industry news and quotes. I miss the old Electronics News weekly tabloid, which was published by the same folks who did Women's Wear Daily, and had a similar gossip/dish level. It was great fun.

EDN is OK. The RF mags, Microwave Journal and RF Design and such, are pretty good.

A string of these will propagate a rather nice ripple of positive pulses. It used to be used in old discrete model-airplane RC transmitters to generate the PPM rf pulse train, with every other base pullup resistor being a joystick pot.

That doesn't meet the specification. We're having to special-order the sloppy 10% regulators as it is...

Jim still hasn't defined the precise numerical value of "zero."

Hello John,

Sometimes it's good. Like the recent backgrounder on Intel by Rick Merritt.

Reminds me of someone who was about to pick up one of these "magazines" next to the grocery counters. The ones where they report how Liz Taylor just showed up somewhere but was abducted by aliens. After being asked whether that would be the right kind of literature: "Well, listen, my mom told my that these guys always know first!"

Some of us sad people enjoy that kind of thing :) The other year, was looking forward to a good read with ...

I measure +2.2mV typical with my cost-effective circuit (Ic/Ib ~= 1, BOM < 0.01 USD).

Hello John,

Really? I dunno, once I am happy with a CAD suite I'll stick with it for a long, long time. EDA stories have about the level of appeal that car ads have on TV. Even our Rottweiler falls asleep.

Sounds like "The genealogy of the screwdriver" or something like that. Man, people seem to write about all kinds of stuff these days :-)

For most people a screwdriver is something you mix and then drink.

Hello John,

It's probably zero +/-3dB :-)))))

Duh? How does ZERO have dB variations ?:-)

I'm sure he actually meant 0 +- 30%

John

Hello Jim,

I knew somebody would take the bait :-)))))

Ask a politician. They can offer a perfectly logical explanation. After all, they usually succeed in convincing their constituency that 2+2=5 when it comes to stuff like pork barrel budgeting.

It seems quite well accepeted in political speak that a spending "cut" actually means "smaller increase than originally planned." :-(
