I've posted a number of PDFs of actual schematics in actual production products. *I* decide what's proprietary. I also post circuit ideas to play with, some serious and some goofy, but you never play. Playing with circuits is a fun sport, like riffing on a jazz theme, but you can't do it.

You never talk about electronics any more. You just whine about personalities. What an old hen.

I don't see why once isn't enough to warrant an apology, but everything since then consists of mutual accusations of incompetence that are nonsense.

And you're too ignorant to understand what's funny about your last statement ;-) ...Jim Thompson

You don't disagree with me on a technical level, because you never say anything intelligent about circuits any more. Which is why your content-free whining makes you an old hen.

I offered an apology. It was refused.

Of course, though any rational person would question Larkin's competence... he NEVER posts EXACT... he specializes in vagueness. ...Jim Thompson

Say something real about electronics.

Design a current source, or say something real about the ones I've posted.

You really are dumber than dogshit.

When I said it in the past, it was just a poke in the ribs.

That status has changed.

You took sides calling me a troll. Is your name Zimmerman?

Lots of petty horseshit oozes from you. Just because this isn't one of those doesn't clear you either.

But yes... triviality has crept into the entirety of Usenet.

It has to do with parentage. Or lack thereof.

See! Total ignorance exemplified ;-) ...Jim Thompson

See! Still zero electronic content.

Sure; it forces the collector current to average what we want it to be, temperature corrected.

For few-percent error tolerance, it's probably fine, but

Think so? It's just a cascode that has the base current corrected for. The emitter resistor should increase the output impedance, kill most of the Early slope.

This one?

Doesn't RRRR act like, well, a resistor? It seems to me, too, that the c-b junction will forward conduct (into the capacitance of the current source) as the ramp runs up.

You do NOT grok electronics.

I know he is an idiot lying narcissistic POS. Just sometimes i see an opportunity to make him display it in full gory.

It may or may not work fine with ideal parts. The real question is what will it do with REAL parts! Your topology is NOT a circuit. What = happens when all resistors are 10 milliohms or 10 gigaohms? No topology works in all cases. Quit the bullshit.

?-)

I have seen you post fragments of something. Never a complete schematic of even a test jig. Interesting scope traces without useful circuit data. Physical test circuit layouts without any other information to make it useful. Not much else. Garbage really.

?-)

You are not in the category of Larkin or anyone else.

That's silly. I post real schematics, from production products, when it's helpful. It's more fun to post new ideas, to play with topologies and parts. Note "design" in the group title.

My stuff may be garbage to you, because the electronics that I do doesn't interest you, like the PHEMT measurments I posted recently. I can't help that.

You don't seem to actually design electronics. You *could* help that.

I didn't say that any values would work; that would be ludicrous.

I did give Jim a simple procedure for finding a working set of resistor values: set them all to one ohm, Spice, see if it works. If not, increase all resistors by 1 ohm and repeat until it does work. Amazingly enough, he's still not satisfied.

I'll leave the capacitor value, as Jim likes to say, "to the student."

You don't seem very satisfied either.

Look, no values. The same goes for any classic circuit in most books. It is ludicrous to say that a topology can't be described without values.
