Abstract: An electronic device and a bias control method thereof are provided. The electronic device includes a channel quality measuring module configured to measure a channel quality of a received signal, a bias offset determining module configured to determine a bias offset based on the measured channel quality, a bias offset applying module configured to modify a bias by applying the determined bias offset to a specified bias value, and a power amplifier configured to amplify transmission power according to the modified bias.
