1. An electronic device, comprising:
a first sampling circuit, being configured to sample a pulse width of a first input pulse of a pulse-width modulated (PWM) input signal since a first time point on a first half of a first pulse period of a clock signal; and
a first summing circuit coupled with the first sampling circuit, being configured to generate a first output pulse of a PWM output signal since a second time point on a second half of the first pulse period, wherein a pulse width of the first output pulse is a summation of the pulse width of the first input pulse and a pulse width of a second input pulse of the PWM input signal, and the second input pulse is a next pulse after the first input pulse.
