Abstract: Provided is a reconfigurable amplifier. The reconfigurable amplifier includes a gain circuit including a gain path configured to amplify an input signal, and a feed forward circuit including a feed forward path configured to receive the input signal and perform feed forward compensation on the input signal, and a first control circuit configured to perform the feed forward compensation in a first mode by activating the feed forward path, and deactivate the feed forward path in a second mode different from the first mode.
