Abstract
저전압 동작 특성을 갖는 커런트 바이어스회로를 공개한다. 그회로는 베이스측이 공통 연결되고, 이미터측의 전원 전압에 공통 연결되는 제 1 및 제 2PNP 형 트랜지스터와, 컬렉터측이 상기 전원 전압과 연결되고, 베이스측이 상기 제 1 트랜지스터의 컬렉터측과 연결되는 제 1 NPN형 트랜지스터와, 이미터측이 상기 제 1 및 제 2 PNP형 트랜지스터의 베이스측에 연결되고, 베이스측이 상기 제 1 NPN형 트랜지스터의 이미터측에 연결되고, 컬렉터측이 접지되는 제 3 PNP형 트랜지스터, 및 상기 제 1 NPN형 트랜지스터와 접지 사이에 연결되는 전류 전원을 포함하는 것을 특징으로 한다. 본 발명에 의하면, 기준 전류와 미러 전류의 차가 작으면서도 저전압에서 동작이 가능하다는 잇점이 있다.A current bias circuit having low voltage operating characteristics is disclosed. The circuit has a first side and a second PNP type transistor commonly connected to a base side, a common side connected to a power supply voltage on an emitter side, a collector side connected to the power supply voltage, and a base side connected to a collector side of the first transistor. A third NPN transistor to be connected, an emitter side to a base side of the first and second PNP transistors, a base side to a emitter side of the first NPN transistor, and a collector side to ground; And a PNP transistor, and a current power source connected between the first NPN transistor and the ground. According to the present invention, it is possible to operate at a low voltage while the difference between the reference current and the mirror current is small.
