Abstract

The embodiment of the invention provides an envelope tracking power supply circuit and electronic equipment, and belongs to the technical field of communication equipment. The envelope tracking powersupply circuit comprises a multi-power-supply-stage circuit, a linear amplification circuit and a multi-phase Buck circuit; the linear amplification circuit is connected with the multi-power-supply-stage circuit and the multi-phase Buck circuit; the multi-power-supply-stage circuit comprises a level providing unit capable of outputting various power supply voltages and a level selection switch unit, and the level providing unit is connected with the linear amplification circuit through the level selection switch unit. According to the embodiment of the invention, the multi-phase technology andthe multi-power technology are combined to realize a switching linear hybrid ET power architecture, and the tracking bandwidth of the ET power supply can be further improved while the high efficiencyis ensured, so that ultra-wideband high-efficiency tracking is realized, and the ultra-wideband high-efficiency communication requirement can be met.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communication equipment, and in particular to an envelope tracking power supply circuit and electronic equipment. Background technique [0002] Currently, the fifth generation mobile communication technology (5 th Generation, 5G) can achieve a transmission rate as high as several Gbps, a delay as low as milliseconds, and a million-level device connection per square kilometer, which will greatly change people's production and lifestyle, and realize smart A large number of related application scenarios will emerge as the times require. [0003] Due to the higher power consumption demand brought by the current 5G electronic equipment, the power amplifier (Power Amplifier, PA) has become the most important energy-consuming device of the RF front-end. At present, in order to improve the efficiency of the PA, electronic equipment generally adopts an envelope tracking (Envelope Tra...
