    • An amplifier apparatus including a first dividing circuit disposed at the input side of an amplifier, for dividing an input signal into a primary signal to be amplified by the amplifier and an auxiliary signal for distortion detection, a distortion compensating signal generating circuit for generating a distortion compensating signal, based on the auxiliary signal and the output of the amplifier, to compensate a distortion component contained in the output of the primary amplifier and inputting the generated signal into the amplifier, and a primary signal combining circuit for combining the primary signal obtained by the first dividing circuit 1 with the distortion compensating signal. The result is that even using an auxiliary amplifier whose gain is small or without using such auxiliary amplifier in a feedback system, the distortion component contained in the output of the amplifier can be effectively compensated.
    • 一种放大器装置,包括设置在放大器的输入侧的第一分频电路,用于将输入信号划分成放大器放大的主信号和用于失真检测的辅助信号;失真补偿信号产生电路,用于产生失真 补偿信号,基于辅助信号和放大器的输出,以补偿包含在主放大器的输出中的失真分量并将生成的信号输入到放大器中;以及主信号组合电路,用于组合由 具有失真补偿信号的第一分频电路1。 结果是,即使使用增益小的辅助放大器或者在反馈系统中不使用这种辅助放大器,可以有效地补偿放大器的输出中包含的失真分量。
