摘要： The present invention relates to an amplifier and, more particularly, to an adaptive linear amplifier with low power consumption and a high linearity. The adaptive linear amplifier according to the present invention comprises amplification means and a bias controller. The amplification means comprises a main transistor and an auxiliary transistor unit. The main transistor and the auxiliary transistor unit are coupled to each other. The bias controller controls a bias voltage applied to the main transistor and the auxiliary transistor unit.
