Can two lateral fets be used instead of one in the CFB arrangement. I was thinking after looking at one of Doug Self's amps (the load invariant), that he used two 2SC3281 in a CFB arrangement (admittedly without voltage gain) but these BJT's are not exactly sluggish parts compared with lateral mosfets. Ft being 30mhz on these parts.
Maybe mosfets are two problematic to do this with, or I am missing something.
Anyway, just thoughts.
