Abstract
Description
Claims (1)
- 전원전압(Vref)에 의해 스위칭되는 트랜지스터(Q1)(Q2) 및 네가티브입력단자(NIN)의 전위에 따라 스위칭되는 트랜지스터(Q3)로 수광다이오드(PD) 및 포시티브입력단자(PIN)를 제어하는 자동 발란스 레벨 제어회로에 있어서, 상기 트랜지스터(Q1)의 에미터를 저항(R1)을 통해 트랜지스터(Q4)(Q5)와 수광다이오드(PD) 및 포시티브입력단자(PIN)에 공통접속함과 아울러 직렬연결된 저항(R2)(R4) 및 이와 병렬연결된 저항(R3)을 통해 각기 트랜지스터(Q4)(Q5)의 에미터에 연결하고, 저항(R2)(R4)의 접속점을 트랜지스터(Q4)의 베이스에 연결한 후 그 트랜지스터(Q3)의 베이스를 전지증폭기의 네가티브입력단자(NIN)에 연결하여 구성함을 특징으로 한 자동 발란스 레벨 제어회로.
