Abstract

A power management circuit supporting phase correction in an analog signal with reduced physical pins is disclosed. The power management circuit includes a power amplifier circuit configured to amplify an analog signal having a time-variant power envelope based on a modulated voltage. The power management circuit also includes an envelope tracking integrated circuit (ETIC) configured to generate the modulated voltage and a modulated phase correction voltage to thereby cause a phase change in the analog signal. The ETIC receives a modulated differential signal that includes a common signal and a differential signal and generates the modulated phase correction voltage and the modulated voltage based on the common signal and the differential signal, respectively. By modulating the common signal and the differential signal into the modulated differential signal, it is possible to reduce physical pins in the ETIC to thereby reduce cost and footprint of the power management circuit.
