| Zusammenfassung: | In an example embodiment, an analog-digital converter includes digital-analog converter, a comparator, and a register. The digital-analog converter is configured to output a differential voltage between a reference voltage and a voltage of an analog signal. The comparator is configured to output a comparison signal corresponding to the differential voltage output by the digital-analog converter. The register is configured to cause the digital-analog converter to generate N pairs of differential voltages (N≧1), to cause the digital-analog converter to generate an (N+1)th pair of differential voltages by causing one of a positive side and a negative side of the digital-analog converter to output an (N+1)th differential voltage and causing the other of the positive side and the negative side to output a differential voltage equal to the Nth differential voltage as an (N+1)th differential voltage, and to output a digital signal corresponding to a comparison signal having a smallest voltage among (N+1) comparison signals. |
