Folks,Have to drive around a hundred pF or so in parallel with maybe a fewhundred ohms blazingly fast. 10-12V amplitude, transitions ideallysub-nanosecond from 10-90% both directions. Not too boutiquish orunobtanium (which excludes certain companies ...) and not more than afew Dollars. Shouldn't introduce noise when low. Low quiescent current,preferably under 20mA.Looked around and the fastest one I could see is this dude:Not too much data but it gets into the 2nsec range. Anyone aware of adriver with even more testosterone?Of course the ideal scenario would be a push-pull MMIC with 15V or moresupply voltage but that ain't going to happen. Same with RF switches,even if they could take 12V they are surprisingly slow in switch action.Ok, could roll my own, of course. But that gets to be involved and a bittoo big for this project.-- Regards, Joerg

The rise/fall times are mediocre. A little series inductive peakingwould help.Gate driver chips are cool, though. They have lots of off-label uses.What's the load? Need DC coupling/long pulses?I know how to get 6 or 7 volts of brutal sub-ns swing cheap, at zeroIq. Could be doubled, depending. Not for public release.John

Super duper hype fast FET driver?

I wasn't making a moral comment, just a rational economic one.

Jim T disregards the very high regard I have for your country (and indeed for his own career achievements) because he's made so much of his living from military projects, and because I detest the self-destructive bully-boy thinking by which he justifies that. Bullying is a sign of weakness and cowardice, Jim, not strength. You're old enough to know that.

I didn't realize the CIA or the IIR was interested in life expectancy during the Medieval Period!?? or back whenever everyone dropped dead at 35 - what poppycock!

Have you seen any "meek inherit the earth"? I don't see myself as a bully, just as a defender. But it's too late now. Time to abandon Tombstone and conducts raids from the sidelines ;-) ...Jim Thompson
