Classification: CPC H  G | IPC G  H

Claim 3:
4. The clock spread spectrum circuit according to claim 3, wherein the duty cycle control signal generation module comprises: a comparison sub-module, a generation sub-module, and an output selection sub-module;
the control word providing module is configured to output the first duty cycle control word and the second duty cycle control word to the comparison sub-module;
the comparison sub-module is configured to judge whether the first duty cycle control word and the second duty cycle control word are equal or not, output the first duty cycle control word and the second duty cycle control word to the generation sub-module and output a first control signal to the output selection sub-module if the first duty cycle control word and the second duty cycle control word are not equal; and output a second control signal to the output selection sub-module if the first duty cycle control word and the second duty cycle control word are equal;
the generation sub-module is configured to generate the duty cycle control signal and output the duty cycle control signal to the output selection sub-module in response to receiving the first duty cycle control word and the second duty cycle control word; and
the output selection sub-module is configured to output the duty cycle control signal generated by the generation sub-module in response to receiving the first control signal, and output a default control signal having a duty cycle that is equal to 1 as the duty cycle control signal in response to receiving the second control signal.
