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 20):
The method of  claim 19 , further comprising:\n setting the second level of the first modulated gate drive signal by a second DC reference voltage generator; and estimating a threshold voltage of a first one of the power transistors and deriving a second DC reference voltage from a difference between the first DC reference voltage and the estimated threshold voltage, by a first DC reference voltage generator.
