Abstract

본 발명은 비교 위상 동안에 기준 신호와 입력 신호를 비교하는 제1 및 제2트랜지스터와 트랜지스터를 통한 정전류의 평형을 맞추는 회로를 포함하는 차동 비교기에 관한 것이다. 상기 회로는 제1트랜지스터의 소스에 접속되는 제1전류원과, 제2트랜지스터의 소스에 접속되는 제2전류원과, 두 트랜지스터의 소스들 사이에 접속되는 선택적으로 동작하는 임피던스 수단을 포함한다.
각 비교 위상에 앞서, 제1 및 제2트랜지스터를 통한 전류는 두 트랜지스터의 게이트에 동일한 전압을 인가하고 제1 및 제2트랜지스터의 소스 퍼텐셜을 교차 결합하여 제2 및 제1전류원을 제어함으로써 평형(즉, 거의 동일)을 이룬다.
