  • Automatic optimization of linearity for envelope feedback RF amplifier linearization
    Publication number: 20020171484
    Abstract: An amplifier configuration and method of amplifying a signal are provided for automatic optimization of linearity of power amplifier input/output characteristics. The amplifier configuration utilizes a feedback loop that includes detecting envelopes of signals that are input and output from a power amplifier. The amplifier configuration includes an offset parameter determined in a second feedback loop that adapts to values for optimizing the linearity of the power amplifier output when input signal amplitudes are within a predetermined range of small signal values, thereby producing a substantially reduced distortion and thus linearized output over the entire input signal amplitude range.
