Strange high frequency push pull transformer action

You said it.

Same comments apply to you as to Spehro.  You need reading glasses.
You must be getting old

what part of it?

that TI part two P-channel fets common source, isn't that what you
want?

Yep. Sorry. Those ARE the same sex :-(

Didn't you just advocate for legalizing that?

That's a complementary pair... separate chips on hybrid substrate. I
used that very device to solve a touch screen power supply issue for
someone up near you where it BLIZZARDS ;-)

A oui bit of snow might be nice for a change- it's getting a bit
dreary with the short days and November rain.

Betcha he finds this:

That would explain the first waveforms, anyhow.

Could be, you would get the same basic appearance in both drains but the
voltage magnitudes would be different.

Still poking around. You guys thoughts and responses are great and
confirming that I'm not crazy.

The transformer guy is saying it is some fancy RF stuff and I don't have
the background to say he's wrong but my gut says its something 1st order
that is the problem.

Somebody needs to tell him 10 MHz hasn't been fancy RF stuff for 75 years.

Huh? It's trivial. I designed a LiIon battery charger chip based on
that very scheme.

Doesn't it mean isolating drains from substrate?

How many eggs does it take to make an omlette?
