Abstract
A feedforward amplifier system including a main amplifier and first and second error amplifiers, and wherein the first error amplifier is itself a feedforward amplifier whose operation is corrected by the second error amplifier. With appropriate selection of circuit components the operating power required by the amplifier system, and hence the size of the package in which it is contained, may be reduced up to one-third.
