Abstract
According to an embodiment, a comparator includes a first transistor, a second transistor, an output stage, and a node group. The first transistor is configured to operate when a first voltage applied thereto exceeds a first threshold value, and is disposed in an input stage. The second transistor is configured to operate when a second voltage applied thereto exceeds a second threshold value and is disposed in the input stage. The output stage is configured to perform voltage switching and output according to the change in the magnitude relationship between the first voltage and the second voltage. The node group is configured to, during a non-operational state in which the first voltage and the second voltage are not compared, vary at least either the first threshold value or the second threshold value.
