Operation of this power amplifier...

  1. Aug 9, 2015 #1
    Please help me on this...

    The following diagram is of a class AB power amplifier ......
    According to text its written that "the voltage drop across R1 and R2 should be minimum in order to produce the base current.But this minimum voltage requirement keeps the amplifier maximum peak output voltage well below the supply voltage level and thus limits the amplifier efficiency"... and thus to compensate this boot strap capacitors are used...

    thanks
