Abstract

An amplifier includes a first lower active sub cell and a second lower active sub cell, each comprising an input terminal and an output terminal, wherein the input terminals of the lower active sub cells are connected to the amplifier input and the output terminals of the lower active sub cells are not shorted. Furthermore, the amplifier includes a first upper active sub cell and a second upper active sub cell, each including a biasing terminal, wherein the input terminals and the output terminals of the upper active sub cells are coupled between the output terminals of the lower active sub cells and the amplifier output. The amplifier includes a bias controller configured to provide a first biasing signal to the first upper active sub cell and a second biasing signal to the second upper active sub cell based on an output power of the output signal.
