Abstract: 감소된 공급 잡음을 갖도록 구성된 가변 이득 증폭기(VGA)가 개시된다.  VGA는 제1 전압 레일과 제2 전압 레일 사이에 결합된 제1 저항기, 제1 FET 및 제1 전류-소스를 포함한다.  VGA는 전압 레일들 사이에 결합된 제2 저항기, 제2 FET 및 제2 전류-소스를 포함한다.  제1 FET 및 제2 FET의 각각의 소스들 사이에 가변 저항기가 결합된다.  제1 또는 제3 전압 레일과 제1 입력 FET 및 제2 입력 FET의 소스들 사이에 각각 가변 커패시터들이 결합된다.  커패시터들이 제1 전압 레일에 결합되는 경우, FET들의 게이트들에 인가되는 입력 차동 신호가 제1 전압 레일에서의 공급 전압으로부터 유도된다면 FET들의 게이트-소스 전압들에 걸쳐 잡음 소거가 발생한다.  커패시터들이 제3 레일에 결합되는 경우, 제3 레일에서의 공급 전압이 더 정확한 조정기에 의해 발생된다면 공급 잡음이 감소된다.
