Abstract: A circuit for use with a power amplifier that amplifies an input signal. The circuit may comprise an amplitude correction circuit and an open-loop switching regulator. The amplitude correction circuit may be configured to generate a corrected envelope signal from an input envelope signal that represents an envelope of the input signal. The open-loop switching regulator may be connected to the amplitude correction circuit and may be for powering the power amplifier based on the corrected envelope signal. According to various embodiments, the corrected envelope signal generated by the amplitude correction circuit is a function of the input envelope signal and an error voltage of the open-loop switching regulator.

Abstract: A method of controlling a multiphase power converter including a plurality of sub-converters coupled to provide power to a load is disclosed. Each sub- converter includes a power switch. The method includes selectively and consistently turning on the power switch of one or more of the sub-converters at substantially a same time as a reference signal representing a desired output of the power converter increases. The method further includes selectively and consistently turning off the power switch of one or more of the sub-converters at substantially a same time as the reference signal representing the desired output of the power converter decreases. Other methods, multiphase power converters and controllers for multiphase power converters are also disclosed.

Abstract: A method of controlling a multiphase power converter including a plurality of sub-converters is disclosed. The method includes, for each of the sub-converters, estimating a current provided by that sub-converter. The method includes selecting one of the sub-converters that is on and determined to have a greatest current as the next sub-converter to be turned off and selecting one of the sub-converters that is off and determined to have a smallest current as the next sub-converter to be turned on. Other methods, multiphase power converters and controllers for multiphase power converters are also disclosed.
