Abstract:
A class-D amplifier includes an output driver, a pulse width modulator, an integrator, and duty cycle control circuitry. The output driver is configured to drive a loudspeaker. The pulse width modulator is coupled to the output driver. The integrator is coupled to the pulse width modulator. The duty cycle control circuitry is coupled to the integrator. The duty cycle control circuitry is configured to monitor amplitude of output signal of the integrator, and change an average duty cycle of signal at an output of the output driver as a function of the amplitude.

Claim (Index 20):
The integrated circuit of  claim 17 , wherein the duty cycle adjustment circuitry is configured to:\n responsive to a determination by the comparing circuit to increase the average duty cycle, increase the average duty cycle in a plurality of steps, wherein each of the steps successively increases the average duty cycle; and responsive to a determination by the comparing circuit to decrease the average duty cycle, decrease the average duty cycle in a plurality of steps, wherein each of the steps successively decreases the average duty cycle; wherein a number of steps applied to increase the average duty cycle by a given amount is fewer than a number of steps applied to decrease the average duty cycle by the given amount.
