Abstract: An electromagnetic interference modulation circuit includes an instruction module, a slew rate adjustment module, and a power stage module. The instruction module outputs a selecting signal according to an instruction signal. The slew rate adjustment module connected to the instruction module is configured to generate a plurality of electromagnetic interference modulation signals, and output an electromagnetic interference modulation signal corresponding to the selecting signal. The power stage module connected to the slew rate adjustment module and an output end is configured to output a voltage signal to the output end according to the electromagnetic interference modulation signal.
