Abstract:
A class D audio amplifier includes a modulator for receipt of an audio signal and converting the audio signal into a modulated audio signal having a predetermined carrier frequency. The class D audio amplifier additionally includes an output stage having a plurality of power transistors coupled in cascade between a first DC supply voltage and a second DC supply voltage, and a plurality of gate drivers configured to generate respective modulated gate drive signals to the plurality of power transistors. A controller is configured to adjust a level of a first modulated gate drive signal applied to a first power transistor of the output stage based on a level of the audio signal.

Claim (Index 19):
The method of  claim 16 , wherein adjusting the level of at least the first modulated gate drive voltage based on the determined level of the audio signal comprises:\n comparing the determined level of the audio signal to a signal level threshold; and selecting a first level of the first modulated gate drive signal if the level of the audio signal is smaller than the signal level threshold, or a second level of the first modulated gate drive signal if the level of the audio signal is larger than the signal level threshold, wherein the second level is larger than the first level.
