  • Power supply apparatus for power amplifier
    Patent number: 10305519
    Abstract: A power supply apparatus for a power amplifier includes a converter configured to convert input power into driving power for the power amplifier, a detector configured to transfer the driving power from the converter to the power amplifier, including an inductor formed on a detection path of the driving power, and configured to detect power information regarding the driving power to generate a detected signal, and a controller configured to control power conversion of the converter based on an envelope signal of a signal input to the power amplifier and the detected signal.
    Type: Grant

  • Multiphase power supply having single comparator
    Patent number: 10193499
    Abstract: A multiphase power supply includes a multiphase converter including first and second converters having differing operating phases, each of the first and second converters configured to convert input power into driving power, and transmit the driving power to a power amplifier, a detector configured to detect a voltage based on the driving power, and a duty controller configured to compare an error voltage between an envelope signal of an input signal input into the power amplifier and the detected voltage and sawtooth wave signals having different phases from each other to generate duty control signals, wherein the duty controller compares the error voltage and the sawtooth wave signals with each other using a single comparator.
