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