Abstract: 본 발명은 입력 단이 이미터 공통 바이폴러 트랜지스터(T 1 ) 또는 소스 공통 전계 효과 트랜지스터를 구비하는 저 잡음 집적 증폭기 회로의 설계 방법에 관한 것이다.  본 발명에 따른 방법에서는 집적 증폭기 회로(1)의 제조 시의 공정 파라미터의 적절히 선택 및/또는 하나 이상의 집적 소자의 기하 파라미터(r b )의 적절한 선택 및/또는 집적 증폭기 회로(1)의 소자의 값의 크기 결정에 의해, 실 제너레이터 저항(R G )에 종속하는 증폭기 회로의 잡음 지수(F(R G ))를 규정 출력 임피던스(Z A )의 실수부의 값도 역시 놓이는 구역에서 규정 잡음 지수(F soll ) 미만으로 되도록 함으로써, 증폭기 회로(1)를 그 증폭기 회로(1)에 선행 접속된 전달 요소(3)의 규정 출력 임피던스(Z A )의 실수부에 잡음 정합시킨다.  또한, 밀러 효과에 기인하여 규정 출력 임피던스(Z A )의 공액 복소수와 동일한 입력 임피던스(Z E )를 생성하는 복소 전압 이득이 얻어지도록 트랜지스터(T 1 )의 컬렉터에 걸리는 유효 부하(Z L )를 선택함으로써 증폭기 회로(1)의 입력 임피던스(Z E )를 필요한 바대로 규정 출력 임피던스(Z A )에 전력 정합시킨다.
