RADIO FREQUENCY (RF) INTEGRATED CIRCUIT PERFORMING SIGNAL AMPLIFICATION OPERATION TO SUPPORT CARRIER AGGREGATION AND RECEIVER INCLUDING THE SAME

A receiver includes an amplification block supporting carrier aggregation (CA). The amplification block includes a first amplifier circuit (600) configured to receive a radio frequency (RF) input signal (RF) at a block node (Z) from an outside source, amplify the RF input signal (RF), and output the amplified RF input signal as a first RF output signal (RF). The first amplifier circuit (600) includes a first amplifier (AMP) configured to receive the RF input signal (RF) through a first input node (X) to amplify the RF input signal (RF), and a first feedback circuit (613) coupled between the first input node (X) and a first internal amplification node (Y) of the first amplifier (AMP) to provide feedback to the first amplifier (AMP).
