Multi-output state hysteresis comparator

The invention provides a multi-output state hysteresis comparator comprising a hysteresis comparator, a plurality of window comparators, simulation switches at the same number as the window comparators, and a multivariable anti-phase adder; input ends of the hysteresis comparator and the window comparators are respectively connected with an input voltage; output ends of the window comparators are respectively connected with input ends of the simulation switches; output ends of the simulation switches are respectively connected with an input end of the multivariable anti-phase adder; an output end of the hysteresis comparator is respectively connected with control ends of the simulation switches and the input end of the multivariable anti-phase adder; an output end of the multivariable anti-phase adder is connected with an output voltage. The single hysteresis comparator can generate a plurality of output states, and solves the disadvantages that a conventional single hysteresis comparator can only output two states; the multi-output state hysteresis comparator can be realized completely through existing circuit modules, is simple in circuit structure, and convenient in adjustment.
