Abstract
종속 증폭기(cascaded amplifier)는 도시된 이중 에미터-결합 증폭기와 같은 종속으로 연결된 다수의 증폭 단으로 구성된다. 제1쌍의 트랜지스터(14,20)는 제한 증폭을 제공하고, 저해 소자(22,24)를 가진 제2쌍의 트랜지스터(16,18)는 선형 증폭을 제공한다. 각각의 트랜지스터 쌍은 전류원(28,26)에 의해 구동되며, 상기 전류원은 절대 온도에 비례하는 (PTAT)전류(IT,IT2)를 공급한다. 상기 작은 신호 증폭은 사실상 온도에 무관하며 제한된 출력의 값은 절대 온도에 비례한다. 후자의 효과는 상기 종속 증폭기의 최종 이중이득단에 트랜스리니어(translinear)가변 전류 이득 증폭기(54,56,58,60)를 포함하므로써 저지되며 , 그에 따라 절대 온도에 반비례하는 방식으로 출력 전압을 변화시키게 된다. 따라서 온도와 거의 무관한 전달 함수가 제공될 수 있다.
