Abstract:
In this paper a novel technique for controlling the output power
in class B amplifiers is presented. The new approach uses the
large-signal sweet-spots that appear in this operation mode, to
optimize the linear behavior of the device and improve the
amplifier power efficiency over the complete control range. A
control strategy, based in a dual bias adjustment along the
sweet-spots loci, is proposed to guarantee, at the same time, high
linearity and high efficiency.
