  1. Dear All

    I need your help on the following issue.

    I have to construct a Class AB - push pull amplifier with MOSFET
    Amplifier should be able to provide 21Watt output power (10.5
    Watt RMS) at 8 ohm load (i.e speaker) .
    The circuit suppose to be able to amplify input signal from 1 Vrms at
    a range of 10 Hz to 40 KHz .

    1) Vdc should not exceed 50 Volts
    2) Dc Current not to exceed 2 Amperes.
    3) Construction of Amplifier should be with MOSFET , even if we can find
    easier ways!

    Your opinion would be reall help for me .

    You might try a couple of the following links. Examples and explanations are
    shown there.

    This one isn't quite what you want, but he talks about some of the design

    This one is a bit over-powered for your needs, and he doesn't give all the
    details, but he covers a lot of good theory:
