I figured out where my copy of "The Art of Electronics" was hiding.
"Driven guard" or "bootstrapped guard" is it.
It's funny that a patent can be granted for the application of that to

OTOH, there is the claim that someone successfully obtained a patent
on a ham sandwich (appropriately disguised in legaleese.)
