Claims (2)
- 내부에 D/A 변환기를 갖고 아나로그 입력신호를 디지탈 신호로 변환하는 A/D변환장치에 있어서,변환개시신호 및 클럭신호에 의해 2진 데이타를 N비트씩 2차에 걸쳐 출력하는 데이타 레지스터와,상기 데이타 레지스터의 출력데이터를 2차에 걸쳐 디코딩하고 전원전압과 접지단 사이에 제 1, 제 2 전원가변회로가 연결되어 기준전압을 분압하는 래더저항 양단의 전압을 가변시키고 1차 A/D변환 종료후 최하위 비트에 해당하는 전압값으로 제 1 전원가변회로가 출력되도록 하고 제 2 전원가변회로의 전압값이 1차 A/D변환 동작시 인가되는 전원전압의 폭과 동일한 폭이 되도록 상기 전압값을 가변제어하는 컨트롤회로로 구성된 D/A변환기와,상기 D/A변환기의 출력신호를 기준신호로 하여 입력되는 아나로그신호를 비교하여 이를 데이터 레지스터를 통해 저장, 출력시키는 비교기를 포함하여 구성되는 것을 특징으로 하는 아나로그/디지탈 변환장치.
- 제1항에 있어서,상기 D/A변환기는 상기 디코더의 출력신호에 따라, 래더저항에 의해 분압된 기준전압을 선택적으로 출력하는 N개의 전송게이트 더 포함하는 것을 특징으로 하는 아나로그/디지탈 변환장치.
