Abstract
완전 스윙 CMOS 출력 버퍼회로(20, 30, 40, 50)는 3.3V 표준 및 5V 표준 서브회로와 같은 양립가능하지 않은 전력공급원 회로를 분리시키고, 공통 외부버스와 침묵 또는 전력강하 버퍼회로의 전력공급원 레일을 분리시킨다. 풀업출력 트랜지스터(PMOSI)는 P형 캐리어 반도체 재료의 기판(PSUB)내에 형성된 N형 캐리어 반도체 재료의 웰(N웰)내에 제조된다. P채널 N웰 분리스위치 트랜지스터(PW1)는 상기 월(N웰) 및 고전위 전력 레일(VCC)사이에 연결된 주전류 경로 및 거의 동상으로 동작하도록 풀업 출력 트랜지스터(PMOS1)의 제어 게이트 노드에 연결된 게이트 노드를 갖는다. N웰 분리 스위치 트랜지스터(PW1)는 고전위 전력 레일(VCC)과 풀업출력 트랜지스터(PMOS1) 웰(N웰)을 분리시킨다. N채널 제어노드 분리 트랜지스터(N1)는 전력 강하시 출력 트랜지스터(PMDS1, NMOS1)의 제어 노드를 서로 분리시키도록 고전위 전력 레일(VCC)에 연결된 제어 노드를 지닌다. P채널 피드백 턴오프 트랜지스터(PPI)는 출력(VOUT)에 발생되는 보다 높은 전위 레벨 신호에 응답하여 출력 트랜지스터(PMOs1, NMOS1)를 턴오프시키도록 고전위 전력 제일(VCC)에 연결된 제어 노드를 지닌다. 지연 방전 회로(DDC)는 전력 강하시 고전위 전력레일(VCC)로부터 과도전하를 방전시킨다.
