Abstract
A comparator includes a current mirror module, a comparison module and a buffering and outputting module. The current mirror module provides a bias current to the comparison module. The comparison module comprises a positive input end, a first negative input end and a second negative input end, the positive input end connects to an external terminal, the first negative input end and the second negative input end input a low threshold voltage and a high threshold voltage, respectively. The comparison module compares a voltage of the positive input end to the low threshold voltage and the high threshold voltage, and outputs a comparison result to the buffering and outputting module.
