Abstract
Provided is an AD converter that is capable of converting a wideband noise signal of several GHz or more into a digital signal and that can be used even when an installation space and power supply are severely limited. The AD converter includes: a comparator () configured to compare an input voltage of an analog signal to a determination voltage; an adjustment unit () configured to shift at least one of the input voltage of the analog signal or the determination voltage; an encoder () configured to output time-series data of one bit based on a result of the comparison obtained by the comparator; a processing unit () configured to calculate a frequency of appearance of an output code included in the time-series data; and a control unit () configured to cause the adjustment unit to operate so that a result of the calculation obtained by the processing unit becomes a predetermined value.
