Claims (3)
- 입력단자(2)와 출력단자(3)간에 제공되며, 베이스는 입력 단자에 연결되고 콜렉터는 제1저항기(R1)를 통해 전원소오스(11)에 차례대로 연결되는 출력단자에 연결되고 에미터는 접지되는 양극 트랜지스터(T)와, 출력단자와 트랜지스터 베이스 간에 연결되는 트랜지스터의 전류이득(β)과 동시에 그값이 변동하는 제2저항기(R2)로 구성되고, 제2저항기의 단자에 걸쳐 병렬로 연결되는 커패시터(C)와, 제2저항기 및 트랜지스터 베이스간에 연결되는 제3저항기(R3)로 또한 구성됨을 특징으로 하는 광대역증폭기.
- 제1항에 있어서,제3저항기(R3)의 값이 제2저항기(R2)의 값보다 낮고, 그에 의해 증폭기 임피던스가 주파수에서 낮음을 특징으로 하는 광대역증폭기.
- 제1항에 있어서,제2저항기(R2)가 핀치-베이스 형태의 저항기 임을 특징으로 하는 광대역증폭기.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
