Multiple level envelope tracking using half bridges

A method, comprising:

• generating one or more power supply modulators using one or more half bridges;
• setting a dead time set for each of the one or more half bridges using one or more logic and dead time adjust circuits;
• and
• providing power amplifier drain voltage based on the one or more power supply modulators.

An electronic device, comprising:

• one or more trackers;
• one or more power amplifiers;
• and
• a processor operably coupled to the one or more trackers and the one or more power amplifiers, configured to cause the electronic device to:
• generate one or more power supply modulators using one or more half bridges;
• set a dead time set for each of the one or more half bridges using one or more logic and dead time adjust circuits;
• and
• provide power amplifier drain voltage based on the one or more power supply modulators.
