Abstract: A low distortion amplifier with an optimization circuit that performs an automated alignment of the amplifier is provided. The optimization circuit includes an extraction circuit designed to extract various signals indicative of the operation of the amplifier under the current operating conditions. A control circuit using information received from the extraction circuit determines the appropriate control settings for key components of the amplifier for the current operating conditions. The optimization circuit ensures that the amplifier output has a desired signal level while also ensuring that the output has minimum or no intermodulation distortion under all operating conditions.
