Original Abstract Submitted
A power amplifier circuit includes a power amplifier configured to amplify radio-frequency signal, a supply voltage terminal coupled to the power amplifier, and a bypass capacitor coupled between ground and a supply voltage path connecting the supply voltage terminal to the power amplifier. A supply voltage (V) is configured to be supplied to the power amplifier through the supply voltage terminal, and the supply voltage (V) is configured to vary across multiple discrete voltage levels within a single frame of radio-frequency signals. The first bypass capacitor has an electrostatic capacity equal to or higher than a specific value that is determined to cause the power amplifier circuit with the first supply voltage to have a higher efficiency than a threshold efficiency. In some exemplary embodiments, the bypass capacitor has an electrostatic capacity equal to or higher than 1.4 nanofarads.
