Abstract: Networks, methods, and circuitries are provided that propagate an actuator signal to a plurality of devices in a respective plurality of voltage domains. The network includes a first signal path disposed between an actuator signal source and a first device. The first signal path includes a first point at which the actuator signal is in a first voltage domain. A second signal path is disposed between the actuator signal source and a second device. The second signal path includes a second point at which the actuator signal is in a second voltage domain. The first voltage domain is different from, and has a fixed relationship to, the second voltage domain. A multi-domain coupling circuitry is connected to the first point and the second point. The multi-domain coupling circuitry is configured to maintain the fixed relationship between the actuator signal at the first point and the second point.

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.

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.
