Abstract
Aspects of the disclosure provide a circuit that includes an envelope processing circuitry and a voltage modulator. The envelope processing circuitry is configured to receive a stream of envelope values of a signal for transmission and output a supply modulation signal in response to the stream of envelope values based on an average-power-tracking (APT) calibration. The voltage modulator is configured to modulate a supply voltage to an amplifier according to the supply modulation signal. The amplifier operates under the supply voltage to amplify the signal for transmission.
