Abstract
An exemplary embodiment of the present disclosure illustrates a modulation method for a switching modulator. Firstly, a data signal is received. Then, a first output signal at a first output side of the switching modulator and a second output signal at a second output side of the switching modulator are generated according to the data signal received, wherein the first output signal is an addition signal of a first pulse signal and the data signal, the second output signal is a second pulse signal, the first pulse signal and the second pulse signal are aligned to a same pulse width, and the pulse width equals to a minimum resolution of the switching modulator.

A modulation method for a switching modulator, comprising:
- receiving a data signal;
- generating a first output signal at a first output side of the switching modulator and a second output signal at a second output side of the switching modulator according to the data signal received, wherein the first output signal is an addition signal of a first pulse signal and the data signal, the second output signal is a second pulse signal, centers of the first and the second pulse signals are aligned to each other, the first pulse and the second signals have a pulse width, and the pulse width equals to a minimum resolution of the switching modulator, wherein the minimum resolution of the switching modulator is 1/(fPWM*2N), wherein fPWM is a frequency of the data signal presented as a pulse width modulation signal, and N is a bit number of the data signal.
