Abstract
A distortion correction device and method for power amplifier are provided. The power amplifier receives an input signal and generates a first output signal. The distortion correction device includes a self-mixing mixer and an adaptive calculator. The method includes steps of: utilizing the self-mixing mixer to receive the first output signal and generate a second output signal based on the first output signal, wherein the second output signal includes a plurality of baseband components corresponding to signal spectrum of the input signal; and utilizing the adaptive calculator to perform an adaptation algorithm to generate a look-up table based on the baseband components.
