The combination of sinusoidal voltage driving with the nonlinear transfer characteristic of a MOS device leads to a gain loss less than 3 dB in a class-B amplifier. These losses can be tolerated if the device gain is high.
The usual way to generate the driving waveform required for a class-B amplifier is to employ a sinusoidal voltage driving waveform combined with the nonlinear transfer characteristics of an active device (conduction for [v.sub.GS](t) > [V.sub.TH], cut off for [v.sub.GS](t) < [V.sub.TH]).
