Abstract
Description
Claims (2)
- 2진 논리값을 갖는 n개의 비트 신호를 입력으로 받아, 상기 비트 신호의 2진 논리값이 모두 “0”인 것을 검출하는 n비트 제로(zero) 검출 회로에 있어서, 각각의 게이트 단자에 상기 n개의 비트 신호가 일대일 대응하여 입력되고, 그 일단으로 전원 전압이 인가되도록 직렬 연결된 n개의 PMOS 트랜지스터군(郡)과; 상기 n개의 PMOS 트랜지스터군(郡)의 타단과 접지 단자 사이에 연결되며, 게이트 단자에는 리세트 신호가 입력되는 NMOS 트랜지스터와; 상기 PMOS 트랜지스터군(郡)과 상기 NMOS 트랜지스터가 연결된 노드에 연결되며, 그 출력단으로 상기 n개의 비트 신호의 제로 검출 결과를 출력하는 래치 회로를 포함하는 것이 특징인 n비트 제로 검출 회로.
- 제1항에 있어서, 상기 래치 회로는 두 개의 인버터의 입출력단이 서로 맞물려 피드백되는 구조로 이루어져, 제1인버터의 입력단에 상기 노드의 신호가 입력되며, 상기 제1인버터의 출력 신호가 제2인버터에 입력되고, 상기 제2인버터의 출력 신호가 상기 제1인버터에 입력되며, 상기 제1인버터의 출력단으로 상기 n개의 비트 신호의 제로 검출 결과를 출력하는 것이 특징인 n비트 제로 검출 회로.
