Zusammenfassung: | Included are an integration circuit unit integrating a difference between a value of an analog input signal and a feedback value, a quantization circuit unit converting an output of the integration circuit unit into a digital value, a first current-steering digital-analog converting unit generating the feedback value in accordance with an output of the quantization circuit unit, and a second current-steering digital-analog converting unit differing from the first current-steering digital-analog converting unit. Also, an output terminal of the first current-steering digital-analog converting unit or an output terminal of the second current-steering digital-analog converting unit is connected to an input terminal of the integration circuit unit. |
