Claims (4)
- 복수의 아날로그입력단자(CH1,CH2)에 각각 인가되는 전압레벨을 선택해서 1개의 공통단자(a)에 공급해 주는 아날로그스위치수단(P1,N1,P2,N2)과, 상기 복수의 아날로그입력단자(CH1,CH2)로부터 상기 공통단자(a)에 대한 전압레벨의 공급이 금지되는 기간이 지난 다음 상기 아날로그입력단자(CH1,CH2)에 대한 선택을 변경시키는 제어수단(12), 상기 공통단자(a)에 대한 전압레벨의 공급이 금지되는 기간중에 상기 공통단자(a)를 소정의 전압레벨로 설정해 주는 초기전위 설정회로(11,21,31) 및, 상기 공통단자(a)의 전압과 기준전압을 비교하는 비교기(1)를 구비하여 구성된 것을 특징으로 하는 아날로그-디지털변환회로.
- 제1항에 있어서, 상기 초기전위설정회로(11)는 게이트단자에 제어신호(φPR)가 입력되면서 소오스단자에는 고전위의 전원(VDD)이 접속된 N챈널트랜지스터(N11)와 이 N챈널트랜지스터(N11)에 접속되어 있으면서 게이트단자와 드레인단자가 상호 접속된 P챈널트랜지스터(P11)로 구성된 것을 특징으로 하는 아날로그-디지털변환회로.
- 제1항에 있어서, 상기 초기전위설정회로(21)는 게이트단자에 제어신호(φPR)가 입력되면서 소오스단자에는 고전위의 전원(VDD)이 접속된 N챈널트랜지스터(N21)와 이 N챈널트랜지스터(N21)에 접속되어 있으면서 드레인단자가 접지에 접속된 N챈널트랜지스터(N22)의 직렬회로로 구성된 것을 특징으로 하는 아날로그-디지털변환회로.
- 제1항에 있어서, 상기 초기전위설정회로(31)는 게이트단자에 제어신호(φPR)가 입력되는 N챈널트랜지스터(N31)와 이 N챈널트랜지스터(N31)와 병렬로 접속되어 있으면서 게이트단자에 상기 제어신호(φPR)가 인버터(32)를 매개해서 반전되어 입력되는 P챈널트랜지스터(P31)로 구성된 아날로그스위치를 매개해서 디지털-아날로그변환회로(2)의 출력전위를 상기 공통단자(a)에 반영시키도록 된 것을 특징으로 하는 아날로그-디지털변환회로.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
