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 81):
Class D amplifier circuitry comprising:\n an input for receiving an input signal; first and second output nodes for driving a load coupled between the first and second output nodes; a first driver stage for switching the first node between a first supply rail and a second supply rail; a second driver stage for switching the second node between the first supply rail and the second supply rail; monitoring circuitry for outputting a mode control signal dependent on an indication of the input signal; and driver control circuitry for controlling the first and second driver stages dependent in part on the mode control signal so as to alter the relative phasing of switching transitions at the first and second output nodes.
