Abstract: A receiver includes an amplification block supporting carrier aggregation (CA). The amplification block includes a first amplifier circuit configured to receive a radio frequency (RF) input signal at a block node from an outside source, amplify the RF input signal, and output the amplified RF input signal as a first RF output signal. The first amplifier circuit includes a first amplifier configured to receive the RF input signal through a first input node to amplify the RF input signal, and a first feedback circuit coupled between the first input node and a first internal amplification node of the first amplifier to provide feedback to the first amplifier.

Abstract: A wireless communication device includes an amplifier block amplifying a radio frequency (RF) input signal. The amplifier block includes: a first amplification unit and a second amplification unit. The first amplification unit amplifies the RF input signal to generate a first RF amplified signal including a first non-linearity factor and a second RF amplified signal including a second non-linearity factor, and combines the first and second RF signals to generate a third RF amplified signal. The second amplification unit receives and amplifies the third RF amplified signal to output an RF output signal corresponding to the at least one carrier.
