Abstract

See full text

Envelope tracking power converter circuitry is configured to receive a supply voltage and simultaneously provide two envelope tracking power supply signals, an envelope tracking power supply signal and an average power tracking power supply signal, or a single envelope tracking power supply signal with improved efficiency. When providing a single envelope tracking power supply signal, an envelope tracking power supply signal is provided to a parallel amplifier in the envelope tracking power converter circuitry to provide multiple levels of envelope tracking which improves efficiency.
