Note to all: Replying to Larkin will _not_ be seen by me. I finally figured out how to kill subthreads, so I have no annoyance whatsoever. ...Jim Thompson
I suppose that was your list of fast CMOS opamps.
...Jim Thompson
Chicken! You are wrong about CMOS amps, and are going off to hide in the back of your coop.
Hallelujah. Let's hope you can keep it up this time.

There are some pretty good ones, though not in the ADA4899 or ADA4817 class. I've got quite fond of the AD8605 series--RRIO but with some real output drive, so they run into ADCs really well.
IBM stuck with bipolar ECL until the early '90s, because of its huge transconductance advantage over CMOS. When they made the switch, which was due to the heat problem, Amdahl (Fujitsu) ate their lunch for one product generation before switching themselves.
An advanced ECL process of that era had about 600 process steps, vs. 300 for CMOS, so the cost delta was pretty significant, but the extra performance made it worthwhile.

Oh, he's killfiled me maybe a dozen times by now, generally after being wrong about something. But he always sneaks and cheats; he can't stand to not know what we're saying about him.
I wanted to know if there are any fast CMOS opamps. I guess not.
Since early toob days, Gm/Co has been a figure of merit. It's essentially the GBW measured in radian frequency. I remember how happy I was (I was of course very young) when frame-grid tubes were invented, something like 4x better than the old cylindrical stuff.
6DJ8 and such. I did some nice trigger circuits, 6DJ8/tunnel diode hybrids.It has its own Wiki page!
Mosfets are pretty bad in this FOM.
Ok, a relatively civil conversation until Jim can't resist throwing an insult into the mix.
Finally a rational act in this "conversation"...
But John can't let this end without trying at least to draw blood.
Indeed, why would anyone wish to comment on electronic simulations in S.E.D?
That is the pattern.
Review the thread. I wanted to talk about CMOS parts.
He starts fights that he always loses, and slinks away from with that "killfile" nonsense. I wonder why.

You completely miss my point. You are more than happy to roll around in the dirt with him or any of the other children.
