ABSTRACT:
An amplifier circuit (10) and a method for increasing linearity of the amplifier circuit. The amplifier circuit (10) has a limiter (13) that generates a phase modulated signal (30) in accordance with a phase modulated component (22) of an RF input signal (20). The amplifier circuit (10) also has an envelope detector (16) that generates an envelope signal (40) in accordance with the amplitude modulated component (21) of the RF input signal (20). A delay compensation circuit (17) receives the envelope signal (40) and generates a lead phase envelope signal (50) and an envelope amplifier (18) receives the lead phase envelope signal (50) and generates a bias signal. An RF amplifier (14) amplifies the phase modulated signal (30) in accordance with the bias signal.
