1. A power amplifying device comprising:
a first amplifier including a plurality of input terminals to which a plurality of voltages are applied, respectively, the first amplifier being configured to output a first output signal;
a second amplifier including a plurality of input terminals to which a plurality of voltages are applied, respectively, the second amplifier being configured to output a second output signal;
a first circuit configured to output a third signal obtained by limiting a magnitude of a voltage value of the first output signal, and a fourth signal obtained by limiting a magnitude of a voltage value of the second output signal; and
a second circuit configured to transmit an average value of a voltage value of the third signal and a voltage value of the fourth signal, as a first feedback voltage to the first amplifier and the second amplifier.
