I'm curious about JFET/MOSFET circuit B class amplifier. When BJT is used we only have those (+/-)0.7V limiting the transistors and causing crossover distortion. But with adding FETs or MOSFETs to the circuit, things rapidly change:
FET class B amplifier: Here JFET in only limited by the pinch-off voltage (not by 0.7V like BJTs) so crossover distortion does not occur. If input voltage exceeds the pinch-off voltage then we only get a signal cutter, right?
MOSFET class B amplifier:
-- Enhancement mode MOSFET: Crossover distortion applies for this one, since we need to turn ON the transistor. But the disadvantage (my opinion) is that crossover distortion is quite wide/large, since the transistors threshold voltage varies from 2V to 4V.
-- Depletion mode MOSFET: Same as for JFET, only that here we can also enhance and deplete the channel, right?
