Abstract

본 발명은 비스위칭 방식을 이용하는 램프 신호 발생기 및 이를 포함하는 이미지 센서에 관한 것으로서, 본 발명의 일 측면에 따르면, 램프 신호 발생기가 개시된다. 아날로그-디지털 변환을 위한 램프 신호를 생성하는 본 발명의 일 실시예에 따른 램프 신호 발생기는, 기준전원을 설정하는 기준전원 설정부; 및 미리 마련된 용량성 소자를 기준전원을 이용해 충전시킨 후 용량성 소자를 방전시키며 상기 전하의 방전 추이를 나타내는 신호를 램프 신호로서 출력하는 램프신호 발생부를 포함한다. 본 발명에 의하면 비스위칭 방식으로 램프 신호를 생성하여, 스위칭 잡음 발생을 원천적으로 제거할 수 있는 장점이 있다.
