Abstract: 복수개의 차동 증폭기로 구성된 위상 전이기, 멀티 플라이어, 전하 펌프 및 바이어스 전압 발생기를 구비하는 직교 클락 발생 장치가 제공된다. 본 발명에 의한 직교 클락 발생장치는, 입력 신호를 위상 전이기에 통과시켜 지연된 신호를 발생시킨다. 이 지연된 신호와 클락 버퍼의 출력 신호를 멀티플라이어와 전하 펌프 등으로 이루어진 지연 제어 회로에 입력시켜 두 신호의 위상차가  90도 보다 작으면 위상 전이기의 지연이 커지도록 하는 신호를, 90도 보다 크면 지연이 작아지도록 하는 신호를 위상 전이기에 보낸다. 위상 전이기는 지연 제어신호에 따라 위상 지연을 결정한다. 이런 피드백과정을 통하여 90도 위상차를 가지는 두 신호 I와 Q가 발생하게 된다. 본 발명에 따른 클락 발생장치는 90도 위상 지연만을 필요로 하기 때문에, 180도 위상전이기를 사용하는 것과 비교해서 지터가 작으며, 또한 소전력과 면적도 작다.
