Abstract

A power supply generating circuit includes a driving voltage generating circuit and a pulse generating circuit, where the driving voltage generating circuit is configured to generate a driving voltage signal, the pulse generating circuit receives the driving voltage signal through a first input end and receives a communication signal through a second input end; at a negative phase stage of the communication signal, the first output end does not output the driving voltage signal, and the pulse generating circuit outputs a charge to an energy storage end, where the charge is input from the first output end.
