Abstract:
The present disclosure relates to Class D amplifier circuitry comprising: an input for receiving an input signal; first and second output nodes for driving a load connected between the first and second output nodes. A first driver stage is provided for switching the first node between a first supply rail and a second supply rail, and a second driver stage is provided for switching the second node between the first supply rail and the second supply rail. The Class D amplifier circuitry also includes first driver control circuitry configured to receive a first carrier wave and control the switching of the first driver stage based in part on the first carrier wave; second driver control circuitry configured to receive a second carrier wave and control the switching of the second driver stage based in part on the second carrier wave; and a carrier wave generator configured to provide the first carrier wave and the second carrier wave. A phase shift between the first carrier wave and the second carrier wave is adjustable responsive to a mode control signal.

Claim (Index 84):
Class D amplifier circuitry according to  claim 81  wherein the monitoring circuitry is configured to generate the mode control signal based on at least one of:\n a signal level of an output signal of the Class D amplifier circuitry; \n an envelope of an output signal of the Class D amplifier circuitry; \n a duty cycle of a signal at the first or second output node; \n a duty cycle of an output signal of the first or second driver control circuitry; \n a received indication of a load attached to the class D amplifier circuitry; \n a received indication of a signal type of the input signal; and \n a received indication that a period of silence has been detected in an input audio signal.
