I was of course thinking of the small ones with integrated gate zeners...
I once got caught with those, designing a resonant driving for a small
class E amplifier. The gate couldn't go bellow ground... Oops
Some gate clamped MOSFETS exist with symmetrical clamp voltage.
Yeah, but that's another resistor and, worse yet, a zener on top of
that. S'pose you could use the kind of FET with gate protection zeners
(assuming they're rated for DC), but that's still a resistor, which puts
it on par with the BJT version..
