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.
