Abstract :
A novel linearised bipolar amplifier topology, integrating both reduction of baseband distortion and self-adaptive biasing techniques, is presented. The linearising circuit suppresses more than 25 dB of the spectral regrowth for the first-order sidelobes and reduces up to 36% DC bias power of the amplifying transistor
