Abstract
Description
Claims (2)
- 전원전압(Vcc)이 트랜지스터(Q1)의 콜렉터에 인가되게 접속함과 아울러 저항(R1)을 통해 그의 베이스 및 트랜지스터(Q2)의 콜렉터에 인가되게 접속하고, 상기 트랜지스터(Q1)의 에미터출력전압이 바이아스전압(VB)으로 인가되게 접속함과 아울러 저항(R2)을 통해 상기 트랜지스터(Q2)의 베이스 및 트랜지스터(Q3)의 베이스, 콜렉터에 공통인가되게 접속하여 구성된 것을 특징으로 하는 전원전압 추종형 바이아스회로.
- 제1항에 있어서, 콜렉터에 전원전압(Vcc)이 인가되는 트랜지스터(Q5)의 베이스 및 에미터를 저항(R1) 및 트랜지스터(Q2)의 콜렉터 접속점과 트랜지스터(Q1)의 베이스에 접속하고, 콜렉터에 전원전압(Vcc)이 인가되는 트랜지스터(Q4)의 베이스 및 에미터를 저항(R2) 및 트랜지스터(Q3)의 콜렉터접속점과 트랜지스터(Q2),(Q3)의 베이스 접속점에 접속하여 구성된 것을 특징으로 하는 전원전압 추종형 바이아스회로.
