I usually can figure out what people mean when they post something new

do anything useful...
Coupling coils and a steep transformation ratio can do that. ... where ultra-low power
consumption and bandwidth requirements clash... best solved
with discretes.
Yes, if transformers are used then power gain can provide voltage gain.
But I think that is a bit overkill for this design.
Actually the ones for power supplies are good candidates.
