  • Method and apparatus for error correction of amplifier
    Patent number: 6476674
    Abstract: An apparatus and a method correct the distortion in the output of a first amplifier (e.g., a switching amplifier) by using a second amplifier (e.g., a linear amplifier) coupled in series with the first amplifier. The output of at least the first amplifier is compared to the input signal to generate an error signal representing the distortion in the output of the first amplifier. The error signal is amplified by the second amplifier to generate a correction signal that is interposed in series with the output of the first amplifier to offset the distortion, thereby generating an output signal having little or no distortion. The apparatus and method include both feedback embodiments and feedforward embodiments.
