Abstract
The invention relates to an amplifier arrangement for amplifying an input signal using a distorting main power amplifier such as one operating as a class AB amplifier. The amplifier can be biased at different operating points. The method and apparatus modify bias control signals to the main amplifier to reduce or minimize the distortion energy added by the main power amplifier. A digitally controlled processor iteratively modifies various control bias signals to adjust the output of the amplifier. Different gain and phase control lines can also be iteratively updated at different rates.
