The invention relates to a dynamic latch comparator which comprises an amplification stage module which is connected with a latch stage module and is used for receiving an input signal and amplifying the input signal, the amplification stage module is connected with a switch transistor in series, and the switch transistor is controlled by the output voltage of the latch stage module; and the latch level module is used for receiving the amplified input signal, comparing the input signal and outputting a comparison result. The switching transistor controlled by the output voltage of the latch stage module is connected in series to the amplification stage module, so that the technical effects of timely disconnecting an unnecessary access to reduce power consumption and improve energy efficiency after the comparison stage is ended are realized. 本发明涉及动态锁存比较器，该动态锁存比较器包括：放大级模块，与锁存级模块连接，用于接收输入信号，并对所述输入信号进行放大处理，其中，所述放大级模块上串联有开关晶体管，所述开关晶体管受所述锁存级模块的输出电压控制；锁存级模块，用于接收经过放大处理的输入信号，并对所述输入信号进行比较处理，输出比较结果。通过在放大级模块上串联受所述锁存级模块的输
