Abstract
Aspects described herein include devices and methods for an envelope tracking power supply. In some aspects, the envelope tracking power supply includes an envelope signal input port, an output power port, an input interface circuit coupled to the envelope signal input port, sensing and conditioning circuitry, and amplifier circuitry coupled between the input interface circuit and the sensing and conditioning circuitry, the amplifier circuitry having one or more control inputs. The envelope tracking power supply additionally includes switcher circuitry coupled to the output of the sensing and conditioning circuitry, and the output power port, and the supply further includes output filter circuitry coupled to the output power port and machine learning circuitry configured to receive state tracking data for performance of a transmit power amplifier (PA) that receives power via the output power port.
