摘要： A distortion compensation amplifier has a distortion detection loop that divides an input signal, amplifies one divided signal with an amplifier and uses the amplified signal and another divided signal to detect a distortion component generated and introduced into the amplified signal in the amplifier. The amplifier additionally has a distortion removal loop that removes the detected distortion component from the amplified signal produced by the amplifier. The distortion detection loop comprises a filter for reducing the distortion component of the amplified signal output by the amplifier that was generated and introduced into the amplified signal in the amplifier and detects the distortion component reduced by the filter. The distortion removal loop removes from the amplified signal the detected distortion component that was produced by the amplifier and reduced by the filter.

摘要： A feedforward distortion compensation amplifier includes an adjusting unit for adjusting a gain and a phase of an input signal, a first amplifier for amplifying a signal outputted from the adjusting unit, a delay unit for delaying the input signal, and a coupler for coupling a signal outputted from the delay unit to a signal outputted from the first amplifier. The feedforward distortion compensation amplifier further includes a first controller which detects a distortion component of the first amplifier to control an operation of the adjusting unit based on the distortion component, and a second controller which determines one distortion level from distortion levels based on a magnitude of the input signal, and compares the determined distortion level with the detected distortion component of the first amplifier to control an amplification rate of the first amplifier based on comparison results.
