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 10):
The class D audio amplifier of  claim 1 , wherein the plurality of power transistors comprises a second power transistor having an opposite polarity of the first power transistor, and driven by a second gate driver, and wherein the controller is configured to adjust an level of a second modulated gate drive signal applied by the second gate driver between gate and source terminals of the second power transistor based on the determined level of the audio signal.
