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 11):
The class D audio amplifier of  claim 10 , wherein the controller is configured to select a first level of the second modulated gate drive signal if the level of the audio signal is smaller than the audio level threshold, and select a second level of the second 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.
