Abstract: One exemplary receiver for a wireless communication system includes signal processing components arranged to generate a receiver output according to a radio frequency (RF) signal. The signal processing components include amplifiers having a class-AB biased amplifier included therein. The signal processing components are disposed in a chip, and the class-AB biased amplifier is an amplifier which processes a signal corresponding to the RF signal before any other amplifier included in the chip. The class-AB biased amplifier has a first amplifier block, a bias circuit and a second amplifier block. The first amplifier block is arranged to receive an input at the input port and generating a first output. The bias circuit is arranged to bias the first amplifier block for a class-AB operation. The second amplifier block is arranged to generate an output at the output port according to the first output.
