ABSTRACT:
An amplifier has a main amplifier circuit with multiple amplification stages, including a driving stage and an auxiliary amplifier circuit with multiple amplification stages, including a driving stage. A splitter circuit splits an input signal to provide path asymmetry in splitting the input signal between the main amplifier path and auxiliary amplifier path. The driving stage of the auxiliary amplifier circuit has a power rating higher than the power rating of the driving stage of the main amplifier circuit to provide a gain asymmetry in the amplifier circuit paths.
