1. A driving device, comprising:
a first complementary metal-oxygen-semiconductor circuit, configured to output a power signal or a pull-down signal according to a first input signal; and
a first comparator, comprising:
a first non-inverting input terminal, coupled to the first complementary metal-oxygen-semiconductor circuit, and configured to receive the power signal or the pull-down signal; and
a first inverting input terminal, configured to receive a first reference signal, wherein the first comparator is configured to compare one of the power signal and the pull-down signal and the first reference signal to provide a first driving signal;
wherein a driving voltage value of the first driving signal is between a high threshold and the power signal, or the driving voltage value is between a low threshold and the pull-down signal;
wherein the high threshold comprises a sum of the first reference signal and a parameter, the low threshold comprises a difference between the first reference signal and the parameter.
