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: A digital envelop tracker for a power amplifier. The digital envelop tracker includes a supply filter for filtering a supply voltage to a power amplifier, a level selection circuitry configured to determine a level of supply voltage based on an instantaneous power of an input data stream, schedule a series of switching events based on the determined level of supply voltage, and generate a level select signal based on the scheduled series of switching events, and a switch for connecting one of supply voltages to the supply filter based on the level select signal. The level selection circuitry schedules a primary switching event of the switch based on the determined level of supply voltage and secondary switching events of the switch delayed with respect to the primary switching event based on the determined level of supply voltage to generate a filter response of the supply filter with smaller peaking.
