Abstract: A comparator for comparing a reference signal with a data signal includes a voltage boosting circuit, a first logic inverting circuit and a second logic inverting circuit. The voltage boosting circuit receives the reference signal to hold a voltage difference during a first time, and receives the data signal to generate a comparing signal according to the data signal and the voltage difference during a second time. The first logic inverting circuit is electrically connected to the voltage boosting circuit, outputs an initial signal to the voltage boosting circuit to hold the voltage difference during the first time, and inverts the comparing signal to output a first voltage signal during the second time. The second logic inverting circuit is electrically connected to the first logic inverting circuit during the second time, and inverts the first voltage signal to output a second voltage signal fed back to hold the comparing signal.
