Abstract

본 발명은 리셋트신호 발생회로로, 소정의 클럭신호를 받아서 발진동작을 스위칭하는 스위칭부와, 일정한 반복 주기를 갖는 톱니파신호를 발진하는 발진부 및 발진부의 발진신호의 기준신호를 비교하여 리셋트신호를 출력하는 비교기로 구성되어 시스템의 전원 온(ON)시나 이상 동작시 시스템을 리셋트시켜주는 회로이다.The present invention relates to a reset signal generation circuit, which compares reference signals of oscillation signals for oscillating parts and oscillating parts for oscillating a sawtooth signal having a predetermined repetition period, a switching unit for receiving a predetermined clock signal and switching an oscillation operation. It is a circuit that resets the system when the system is powered on or abnormally operated.
