Abstract

이 발명은 MR 센서로부터 검출된 신호를 기준전원에 따라 1차 증폭하는 제1증폭기와, 상기 제1증폭기로부터 증폭된 검출신호를 인가 받아서 디지탈 신호로 변환 출력하는 슈미트 증폭기로 구성되어서 검출신호에 대하여 진폭성분과 노이즈 성분을 제거하여 출력할 수 있는 모터의 속도 검출신호 처리회로에 관한 것이다.The present invention comprises a first amplifier for firstly amplifying a signal detected from an MR sensor according to a reference power supply, and a Schmitt amplifier for receiving the amplified detection signal from the first amplifier and converting the signal into a digital signal. The present invention relates to a motor speed detection signal processing circuit capable of removing and outputting an amplitude component and a noise component.
