Abstract
A reconfigurable amplifier configured to decrease radio frequency (RF) signal distortion and increase dynamic range is disclosed. The reconfigurable amplifier includes an amplifier having an RF signal input, an RF signal output, and a bias signal input. A distortion detection network has a detector input coupled to the RF signal output and a detector output, wherein the distortion detector network is configured to generate a detection signal that is proportional to distortion at the RF signal output. A bias controller has a detection signal input coupled to the detector output and a bias output coupled to the bias signal input. The bias controller is configured to generate a bias signal that dynamically shifts level at the bias output to reduce the distortion at the RF signal output in response to the detection signal.
