Abstract
A system including an amplifier circuit configured to amplify an input and generate an output, a bias circuit configured to bias the amplifier circuit, and a feedback circuit configured to generate feedback based on the input and the output, and to adjust the bias of the amplifier circuit based on the feedback to reduce amplitude nonlinearity in the output. A digital pre-distortion circuit is configured to reduce phase nonlinearity in the output.
