  • Low distortion amplifier circuit with improved output power
    Patent number: 5917375
    Abstract: A low distortion amplifier circuit employing a main amplifier and a correction amplifier in a feed-forward loop, is particularly adapted for amplifying multi-tone signals. The main amplifier produces fundamental frequency power along with undesirable distortion products. The correction amplifier provides correction signals at the distortion product frequencies to cancel the distortion products of the main amplifier. In addition, the correction amplifier produces fundamental frequency power which is combined with the fundamental frequency power of the main amplifier, thereby increasing the amplifier circuit output power.
