Claims (1)

소정의 상수전압(Vref1)이 게이트단자로 인가되어 전류원으로서의 작동을 하는 트랜지스터(M1)와, 상기 트랜지스터(M1)에 공통접속되어 디지탈 신호의 입력에 따라 그에 상응하는 스위칭동작을 수행하여 아날로그 출력값을 만들도록 하기 위한 양 트랜지스터(M2 및 M3)를 가지는 D/A변환기의 디지탈제어용 전류스위치에 있어서, 서로 상반된 신호를 동일한 시간에 상기 양 트랜지스터(M2 및 M3)의 각 게이트단자로 인가되도록 함과 아울러 기준치와 소정의 차이를 가지는 디지탈 신호가 입력되더라도 이를 보상할 수 있도록 되어진 래치회로수단(1)과 ; 하나의 디지탈 신호를 입력으로 하여 상기 래치회로수단(1)의 구동을 위한 제 1 및 제 2 게이트회로수단(2 및 3)이 구비된 것을 특징으로 하는 D/A변환기의 아날로그값 출력용 전류스위치.A predetermined constant voltage Vref1 is applied to the gate terminal to operate as a current source, and is commonly connected to the transistor M1 to perform a corresponding switching operation according to the input of a digital signal to thereby obtain an analog output value. In the digital control current switch of the D / A converter having both transistors M2 and M3 for making, a signal opposite to each other is applied to each gate terminal of the transistors M2 and M3 at the same time. Latch circuit means (1) adapted to compensate for a digital signal having a predetermined difference from a reference value even if it is input; A current switch for outputting an analog value of a D / A converter, comprising first and second gate circuit means (2 and 3) for driving the latch circuit means (1) by inputting one digital signal. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
