Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 15:
16. A power management apparatus comprising:
a transceiver circuit configured to generate a time-variant power envelope of an analog signal and a time-variant target voltage corresponding to the time-variant power envelope;
a power management circuit comprising:
a voltage processing circuit configured to:
determine a temporal offset between the time-variant power envelope and the time-variant target voltage; and
generate a time-variant modified target voltage that is time-adjusted relative to the time-variant power envelope to thereby substantially reduce the determined temporal offset between the time-variant target voltage and the time-variant power envelope; and

a power management integrated circuit (PMIC) configured to generate a time-variant voltage based on the time-variant modified target voltage; and

a power amplifier configured to amplify the analog signal based on the time-variant voltage.
