Abstract
According to an embodiment, an analog-to-digital converter includes a voltage generating unit, and a plurality of comparators. The voltage generating unit is configured to divide a reference voltage by a plurality of variable resistors to generate a plurality of comparative voltages. Each of the plurality of comparator is configured to compare any one of the plurality of comparative voltages with an analog input voltage and output a digital signal based on a result of a comparison between the comparative voltage and the analog input voltage. Each of the plurality of variable resistors includes a plurality of variable resistive elements that are connected in series, and each of the plurality of variable resistive elements has a resistance value that is variably set according to an external signal.
