Abstract:
Pulse width modulation (PWM) driver circuitry comprising: a loop filter configured to receive an analog input signal and to output a digital loop filter output signal based on the analog input signal and an analog feedback signal; and a PWM modulator configured to receive a digital signal based on the digital loop filter output signal and to output a PWM signal, wherein the PWM driver circuitry further comprises a feedback path coupled to an output of the PWM driver circuitry for the analog feedback signal.
