Dynamic comparator circuit

The invention discloses a dynamic comparator circuit, which comprises a first amplification module, a voltage clamping module, an isolation module, a second amplification module, a trigger module and a clock signal generation module, and is characterized in that the clock signal generation module is provided with a plurality of clock signal output ends; the first amplification module is electrically connected with the voltage clamping module and the isolation module, and is used for amplifying the difference value of the voltage signal to obtain a difference value signal; the voltage clamping module is used for clamping the difference signal at a preset level value; the isolation module is switched between an isolation working state and a conduction working state according to the level value of the clock signal, and transmits a difference signal to the second amplification module; the second amplification module carries out secondary amplification on the clamped difference signal; and the trigger module sampl
