ABSTRACT:
A supply voltage to a power amplifier is controlled. A signal at a single point in a power amplifier is detected. A signal parameter is determined for the detected signal. The signal parameter is compared to at least one predetermined limit. This comparison result is used to determine whether to adjust a supply voltage to the power amplifier. The signal parameter is, for example, an average power or a peak-to-average power ratio.
