Zusammenfassung:A vector sum circuit and a phase controller including the vector sum circuit are provided. The vector sum circuit includes an amplifier for amplifying an input quadrature signal using a first field effect transistor; and a self body-biasing circuit including a resistor which connects the drain and the body of the first field effect transistor to reduce a voltage applied to the body as the current of the drain increases. It is possible to adjust phase independently. 벡터 합 회로, 그 벡터 합 회로를 포함하는 위상 제어기가 제공 된다. 벡터 합 회로는 입력된 직교 신호를 제1 전계 효과 트랜지스터를 이용하여 증폭하는 증폭기 및 제1 전계 효과 트랜지스터의 드레인(drain)과 바디(body)를 연결하여, 드레인의 전류가 증가함에 따라 상기 바디에 인가되는 전압을 감소시키는 저항을 포함하는 자기 바디-바이어스(self body-biasing) 회로를 포함한다.
