Abstract
The present invention discloses a hysteresis comparator comprising an input stage, a hysteresis current generating circuit and an output stage. In the operation of the hysteresis comparator, the input stage is configured to receive a pair of differential input signals to generate at least one differential current signal; the hysteresis current generating circuit is configured to generate at least one hysteresis current to adjust the differential current signal to generate an adjusted differential current signal, wherein the hysteresis current generating circuit includes a common mode voltage detecting circuit for detecting a common mode voltage of the differential input signal for generating the hysteresis current; and the output stage is configured to generate an output signal according to the adjusted differential current signal.
