Abstract
A power amplifying apparatus includes a power circuit configured to generate operating power, a random pulse generation circuit configured to be supplied with the operating power and to generate a pulse width modulation signal of which a pulse width is randomly changed over time using an input radio frequency (RF) signal, and a charge pump circuit configured to be supplied with the operating power and to randomly perform a switching operation according to the pulse width modulation signal to generate a negative voltage.
