Abstract
A differential power amplifier comprises an envelope tracking power supply configured to provide an envelope power supply signal to the differential power amplifier. The differential power amplifier also comprises an input stage configured to provide a differential signal having a first portion and a second portion to a differential output stage. The differential output stage comprises a first output stage amplifier configured to receive the first portion of the differential signal at a first output stage input and provide a first amplified signal at a first output stage output, as well as a second output stage amplifier configured to receive the second portion of the differential signal at a second output stage input and provide a second amplified signal at a second output stage output. The envelope power supply signal provides power for amplification.
