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 1):
A class D audio amplifier, comprising:\n an input node or terminal configured to receive an audio signal; a modulator configured to receive the audio signal and convert the audio signal into a modulated audio signal having a predetermined carrier or modulation frequency; an output stage comprising a plurality of power transistors coupled in cascade between a first DC supply voltage and a second DC supply voltage; a plurality of gate drivers comprising respective inputs coupled to the modulated audio signal and configured to generate respective modulated gate drive signals to the plurality of power transistors for repeatedly switching each power transistor between a conducting state and a non-conducting state; and a controller configured to determine a level of the audio signal and adjust a level of a first modulated gate drive signal of a first power transistor of the output stage based on the determined level of the audio signal.
