Abstract
In some examples, a differential comparator includes a differential amplifier configured to output differential output signals, a first switch portion configured to input the differential output signals from the differential amplifier and output the differential output signals from output terminals while alternatively changing over the output terminals, a latch portion configured to update and latch the differential output signals from the output terminals of the first switch portion, and a second switch portion configured to input output signals from the latch portion and output the latched output signals. The first switch portion and the second switch portion are changed over complementarily so that the differential output signals from the differential amplifier are always outputted from the same first and second output terminals of the second switch portion respectively.
