Title:
PULSE WIDTH MODULATION CIRCUIT, MODULATION METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/208640
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of communications, and provides a pulse width modulation circuit, a modulation method, and an electronic device. In the pulse width modulation circuit, on the basis of an obtained target duty cycle, a control word provision circuit can generate two target frequency control words the ratio of which is the target duty cycle, and output the two target frequency control words to a pulse generating circuit; and the pulse generating circuit can output a target pulse signal of the target duty cycle under the control of the two target frequency control words. Since the control word provision circuit can flexibly generate target frequency control words on the basis of a required target duty cycle, the pulse generating circuit can reliably generate a pulse signal of the target duty cycle on the basis of the target frequency control words, and the flexibility with which the pulse width modulation circuit generates a pulse signal is good.
