Abstract: Provided is a power amplifier installed in wireless communication terminals and systems. According to one aspect of the present invention, a reconfigurable power amplifier capable of selecting a wide band frequency is provided. The reconfigurable power amplifier includes input transistors receiving a radio frequency (RF) signal and a reconfigurable adaptive power cell configured to select the wide band frequency by applying a common-gate bias voltage to a plurality of common-gate transistors with a plurality of separate common gates to amplify the RF signal.
