Claims (5)
- 2상클록신호(Ø*, Ø)에 의해 동작이 제외되는 CMOS다이나믹회로(40)를 갖춘 반도체집적회로에 있어서, 상기2상 클록신호(Ø*, Ø)의 신호원인 클록신호(Ø)가 온/오프를 되풀이하고 있는가 아닌가를 판별하여 그 클록신호(Ø)가 정지상태로 된 경우를 검출해 내는 클록정지검출회로(3, 4)(3', 4')와, 이 클록정지검출회로(2,4)(3'4')의 검출출력(a1,a2)을 받아들여서 상기 2상클록신호(Ø*, Ø)f, f 동일한 논리레벨로 설정/제어하는 클록레벨제어회로를 구비하여 구성된 것을 특징으로 하는 반도체집적회로.
- 제1항에 있어서, 상기 2상클록신호(Ø*, Ø)를 생성해나기 위한 클록버퍼(2)내에 상기 클록레벨제어회로용 게이트회로(7, 9)가 설치된 것을 특징으로 하는 반도체집적회로.
- 제1항에 있어서, 상기 클록정지검출회로(3, 4)(3', 4')는 상기 클록신호(Ø*, Ø)가 입력되는 인버터회로와 이 인버터회로의 출력단과 소정전위단간에 접속된 캐패시터(C1, C2)를 갖추어 구성된 것을 특징으로 하는 반도체집적회로.
- 제1항에 있어서, 상기CMOS 다이나믹회로(40)의 출력단과 소정전위단간에 상기 클록정지검출회로(3, 4)(3', 4')의 검출출력(a1, a2)에 의해 그 온상태가 제어되는 MOS 트랜지스터(6)가 설치된 것을 특징으로하는 반도체집적회로.
- 제1항에 있어서, 상기 신호원으로 사용되는 클록신호(Ø)가 집적회로칩의 외부로부터 공급되는 것을 특징으로 하는 반도체집적회로.
