Abstract
Description
Claims (2)
- 입력 신호의 게인을 조정하는 오피앰프(OP1), (OP2)를 신호라인에 연결하고 상기 오피앰프(OP1), (OP2)의 출력신호는 앰프(AMP1), (AMP2)에서 증폭된후 출력되게 구성한 신호 출력회로에 있어서, 상기 오피앰프(OP1), (OP2)의 비반전단자(+)와 출력단자에는 트랜지스터(Q1), (Q2)의 에미터와 콜렉터를 연결하고 상기 트랜지스터(Q1), (Q2)의 베이스에는 브리더 저항(R2-R7)을 연결하는 한편 PWM펄스를 직류전압으로 변환시키는 제어부(5)를 연결하여 구성시킨 2출력의 균형 조정회로.
- 제1항에 있어서, 제어부(5)는 출력 조정용 PWM펄스를 반전 및 비반전시키는 인버터(IV1)와 버퍼(B1)를 구비하고 상기 인버터(IV1)와 버퍼(B1)를 통과한 PWM 펄스를 직류전압으로 변화시키는 저역 통과 필터(1), (2)를 구비하며 상기 저역 통과 필터(1), (2)의 출력은 트랜지스터(Q1), (Q2)의 베이스에 인가되게 연결 구성시킨 2출력의 균형 조정회로.
