Zusammenfassung:The utility model discloses a quick response developments latch comparator, including the tail switch element, in advance the amplification and input unit, in advance enlarge the reset unit, input unit latchs, cross coupling latchs constitutional unit, isolator unit, latchs reset unit and positive feedback Unit. The isolator unit ended in the stage of reseing to make the PMOS pipe bars current potential of cross coupling in latching the structure for ground GND under the effect of latched input NMOS geminate transistors, it be VDD to make the NMOS pipe bars current potential of cross coupling in latching the structure under the effect of latching the PMOS geminate transistors that resets, and make cross coupling latch the structure and establish the positive feedback rapidly when getting into relatively the stage, and then improvement comparator speed. The utility model discloses can be under the prerequisite that does not increase the consumption, improved traditional pair of tail developments latch the comp
