DISTORTION CORRECTION DEVICE, AMPLIFIER DEVICE, AND WIRELESS COMMUNICATION DEVICE

摘要

This distortion correction device (14) comprises a distortion correction unit (3) which carries out a distortion correction of an amplifier (2) which amplifies a signal (x), and an A/D converter (11) which A/D converts an output signal (y) outputted by the amplifier (2) and provides the same to the distortion correction unit (3). The A/D converter (11) A/D converts the output signal (y) at a low sampling rate which is lower than a sampling rate of a D/A converter (4) which D/A converts a signal which is provided to the amplifier (2). The distortion correction unit (3) carries out the distortion correction on the basis of the signal (x) and the output signal (y) which is A/D converted at the low sampling rate.
