An electronic class-D amplifier including a pulse width modulator and a servo-loop amplifier characterized in that there is provided a sample and hold element which samples a signal at the sample input when a sample command signal is applied to a control input, and holds the value of the last sampled value of the signal at the sample input when a hold command signal is applied to the control input, and the output of the sample and hold element is connected to a modulation input of the pulse width modulator wherein a negative feedback path connects an output of the output switching stage to an input of the servo-loop amplifier.
