Abstract
Systems and methods are provided for dynamically biasing power amplifiers. A power amplifier (PA) that amplifies an input signal may be controlled based on processing of the input signal. The controlling may include adjusting biasing applied to the power amplifier (PA). The processing of the input signal may include applying clipping to the input signal and determining one or more parameters of the input signal. The biasing applied to the power amplifier (PA) may be adjusted based on the one or more parameters of the input signal. The clipping may be configured such that signals applied to positive and negative sides of the power amplifier (PA) are not differential.
