Title:
POWER CIRCUIT AND METHOD FOR SUPPLYING POWER SUPPLY VOLTAGE
Document Type and Number:
WIPO Patent Application WO/2023/153460
Kind Code:
A1
Abstract:
A power circuit (1) comprises a switched capacitor circuit (20) configured to generate a plurality of discrete voltages on the basis of an input voltage, a power modulator (30A) configured to selectively output, to a power amplifier (2A), at least one of the plurality of discrete voltages on the basis of an envelope signal of a high-frequency signal (S1), and a power modulator (30B) configured to selectively output, to a power amplifier (2B), at least one of the plurality of discrete voltages on the basis of an envelope signal of a high-frequency signal (S2), wherein the power amplifier (2A) is configured to amplify the high-frequency signal (S1), the power amplifier (2B) is configured to amplify the high-frequency signal (S2), the high-frequency signal (S1) is a cellular network signal, and the high-frequency signal (S2) is a WLAN signal.
