Embodiment 1
[0047] Such as figure 1 and 2 As shown, this embodiment provides a comparator, and the comparator includes:
[0048] The input pair tube 101 includes a positive terminal input tube M1 and a negative terminal input tube M2 for inputting the positive terminal signal IN+ and the negative terminal signal IN- to be compared;
[0049] The hysteresis control module 102 is connected to the source of the positive input transistor M1 and the source of the negative input transistor M2, and is used to control the positive input transistor when the input pair transistor 101 is an NMOS transistor. The source of M1 or the source of the negative input transistor M2 injects a set current Ix to control the hysteresis voltage; The source of the negative input transistor M2 draws a set current Ix to control the hysteresis voltage.
[0050] As an example, such as figure 1 and 2 As shown, the comparator also includes: a load module 103 and a current bias module 104; when the input pair tube 10...
