Abstract
Description
Claims (4)
- 제1 및 제2신호 각각의 입력에 따라 펌핑전압을 출력하도록 구성하는 챠지펌프 회로에, 동일한 캐패시터 용량을 갖는 펌핑회로인 제1 및 제2펌핑 회로가 직렬로 접속되는 제1펌프 스트링과, 또다른 캐패시터 용량을 갖는 펌핑회로인 제3 및 제4펌핑회로가 직렬 접속되는 제2펌프 스트링과, 상기 제1펌프 스트링의 제1 및 제2펌핑 회로 사이의 노드(N1) 및 상기 제2펌프 스트링의 제3 및 제4펌핑 회로 사이의 노드(N2)를 공통으로 하여 출력전압이 출력되도록 구성되는 것을 특징으로 하는 챠지펌프 회로.
- 제1항에 있어서, 상기 제1 및 제2펌프 스트링 각각은 다수의 펌핑 회로들이 직렬 접속된 것을 특징으로 하는 챠지펌프 회로.
- 제2항에 있어서, 상기 제1 및 제2펌프 스트링의 출력이 180°의 위상차를 갖도록 구성된 것을 특징으로 하는 챠지펌프 회로.
- 제1항에 있어서, 상기 제1 및 제2펌프 스트링에 서로다른 용량의 캐패시터형 트랜지스터가 사용되어 제1단계에서 일정전위까지 전압을 빠르게 상승시키고, 제2단계에서 원하는 전압레벨로 단계적으로 전압을 상승시킬 수 있도록 구성되는 것을 특징으로 하는 챠지펌프 회로.
