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 17):
The method of  claim 16 , further comprising:\n selecting a second fixed level of the first modulated gate drive voltage for levels of the audio signal exceeding the audio level threshold; and selecting a first fixed level of the first modulated gate drive voltage for levels of the audio signal below the audio level threshold.
