Abstract: A voltage converter system is disclosed. The system has a control unit, a multiphase converter, and a measuring unit. The control unit is configured to generate one or more converter parameter adjustments from a feedback signal. The multiphase converter is configured to selectively generate an output signal at a selected voltage and to adjust one or more converter parameters using the one or more converter parameter adjustments to mitigate generation of spurs in the output signal. The measuring unit is configured to measure the output signal and generate the feedback signal from the output signal.

Abstract: Systems, methods, and circuitries are provided for generating a power amplifier supply voltage based on a target envelope signal for a radio frequency (RF) transmit signal. An envelope tracking system includes a first selector circuitry and predistortion circuitry. The first selector circuitry is disposed in a selector module and is configured to input a plurality of voltages conducted on a first plurality of power lanes, wherein the first plurality of power lanes is part of a power distribution network; select a voltage from the plurality of voltages based on the target envelope signal; and provide the selected voltage to a supply lane connected to an input of the power amplifier that amplifies the RF transmit signal. The predistortion circuitry is configured to modify the RF transmit signal based on a selected power lane of the first plurality of power lanes that conducts the selected voltage.

Abstract: Systems, methods, and circuitries are provided for generating supply voltages for a power amplifier in a digital envelope tracking system. In one example, a voltage generation circuitry converts a source voltage into a supply voltage based on a target voltage. The voltage regulation circuitry includes an adjustable boost circuitry that multiplies the source voltage to generate an input voltage having a voltage equal to or greater than the source voltage and a step-down regulator circuitry that regulates the input voltage to generate a regulated output voltage having a voltage that is less than or equal to the input voltage. A voltage splitter circuitry is coupled to the regulated output voltage and is configured to generate at least one derived output voltage from the regulated output voltage. A supply modulator provides a selected one of the at least one derived output voltage to a power amplifier.
