Claims (3)
- 트리플 웰 구조를 갖는 반도체 장치의 래치업을 방지하기 위한 백바이어스 전압 발생기에 있어서,소정 주기의 클락 신호를 발생시키는 오실레이터와,상기 오실레이터로부터 출력되는 상기 클락 신호를 수신하여 백바이어스 전압을 발생시키는 백바이어스 전압 발생 수단과,상기 백바이어스 전압 발생 수단의 출력단 벌크 영역에서 초래되는 래치업을 방지하기 위하여 상기 백바이어스 전압 발생 수단의 상기 벌크 영역에 네거티브 전압을 공급하기 위한 펌핑 수단을 구비하는 것을 특징으로하는 백바이어스 전압 발생기.
- 제 1 항에 있어서, 상기 벌크 영역에 공급되는 상기 네거티브 전압은 상기 벌크 영역에 형성되는 PN 접합의 턴온을 방지하기 위하여 공급되는 것을 특징으로하는 백바이어스 전압 발생기.
- 제 1 항에 있어서, 상기 오실레이터 위상이 반대인 제 1 및 제 2 클락 신호를 출력하며, 상기 백바이어스 전압 발생 수단은 상기 제 1 및 제 2 클락 신호에 의하여 펌핑되는 것을 특징으로하는 백바이어스 전압 발생기.
