1. A method for biasing of a power amplifier circuit, the method comprising:

  • computing a value for a variable bias current based on a selected bias slope value;

    generating an output signal by amplifying an amplifier input signal, wherein a level for said amplifying is determined based on at least said variable bias current;

    generating a feedback signal based on said output signal;

    generating a predistortion signal based on said feedback signal; and

    generating a subsequent output signal based on said predistortion signal and said amplifying.
