本申请涉及电路控制技术领域，公开了电荷泵电路、电荷泵电路的调制方法及非易失存储芯片。该电荷泵电路中的模式控制模块连接电荷泵模块和调制模块，并接收模式选择信号，模式控制模块的输出端连接调制模块的输入端并作为电荷泵电路的第二输出端；模式控制模块基于电荷泵模块的输出和模式选择信号，向调制模块输出对应的采样信号，经过调制模块和电荷泵模块的反馈调制，以在第二输出端将采样信号调制稳定为第二电压进行输出，并使电荷泵模块在第一输出端稳定输出匹配第二电压的第一电压。通过上述方式，能够输出两个相同或者不同的电压，进而减少非易失存储芯片内的电荷泵电路的数量，以此减少非易失存储芯片的功耗和成本。 The invention relates to the technical field of circuit control, and discloses a charge pump circuit, a modulation method of the charge pump circuit and a nonvolatile memory chip. A mode control module in the charge pump circuit is connected with a charge pump module and a modulation module and receives a mode selection signal, and the output end of the mode control module is connected with the input end of the modulation module and serves as the second output end of the charge pump circuit; the mode control module outputs a corresponding sampling signal to the modulation module based on the output of the charge pump module and a mode selection signal, and modulates and stabilizes the sampling signal at a second output end i
