Abstract:
An envelope tracking system for controlling a power amplifier supply voltage includes envelope circuitry and a feed forward digital to analog converter (DAC) circuitry. The envelope circuitry is configured to generate a target envelope signal based on a selected power amplifier supply voltage. The feed forward DAC circuitry includes a voltage source circuitry and a selector circuitry. The voltage source circuitry is configured to generate a plurality of voltages. The selector circuitry is configured to select one of the plurality of voltages based at least on the target envelope signal. The feed forward DAC circuitry is configured to provide the selected voltage to a supply voltage input of a power amplifier that amplifies a radio frequency (RF) transmit signal.

Claim (Index 1):
An envelope tracking system for controlling a power amplifier supply voltage or bias, comprising:\n a voltage source circuitry configured to generate a plurality of voltages; a selector circuitry configured to select one of the plurality of voltages based on a target envelope signal that is associated with an envelope of a radio frequency (RF) transmit signal, wherein the selector circuitry is configured to output the selected voltage for coupling to a supply voltage input or a bias input of a power amplifier that amplifies the RF transmit signal, wherein the target envelope signal includes voltage information that identifies which of the plurality of voltages to select, and wherein the target envelope signal includes time information associated with a time the selected voltage is output from the selector circuitry.
