Abstract: An improved Class-D amplifier may include a digital PWM modulator that receives a digital audio signal and that provides a PWM signal as an input to an analog PWM modulator of the Class-D amplifier. A digital PWM modulator may be configured to receive a digital signal and to generate a first PWM signal based on the digital signal. A digital PWM driver may be coupled to the digital PWM modulator. The digital PWM driver may be configured to receive the first PWM signal and to generate a reference PWM signal based on the first PWM signal. An analog PWM modulator may be coupled to the digital PWM driver. The analog PWM modulator may be configured to receive the reference PWM signal and to generate an output PWM signal based on the reference PWM signal.
