Zusammenfassung:The present invention relates to a touch circuit for stably maintaining an output voltage level by using a transistor, comprising: a first drive transistor (T1) having a drain electrode and a gate electrode connected to input power source (VDD), and having a source electrode connected to the drain electrode of a second drive transistor (T2); and the second drive transistor (T2) having the gate electrode connected to one electrode of a capacitor of which the other electrode is connected to the input power source (VDD), having the drain electrode connected to the source electrode of the first drive transistor (T1), and having the source electrode connected to the ground. La présente invention concerne un circuit tactile permettant de maintenir de manière stable un niveau de tension de sortie à l'aide d'un transistor, comprenant : un premier transistor d'attaque (T1) ayant une électrode de drain et une électrode de grille connectée à une source d'alimentation d'entrée (VDD), et ayant une électrode de source connectée à l'électrode de drain d'un second transistor d'attaque (T2) ; et le second transistor d'attaque (T2) ayant l'électrode de grille connectée à une électrode d'un condensateur dont l'autre électrode est connectée à la source d'alimentation d'entrée (VDD), ayant l'électrode de drain connectée à l'électrode de source du premier transistor d'attaque (T1), et ayant l'électrode de source connectée au sol. 본 발명은, 트랜지스터를 이용하여 안정적으로 출력전압 레벨을 유지하는 터치 회로에 관한 것으로, 입력 전원(VDD)에 드레인 전극과 게이트 전극이 연결되고, 하기 제2 구동 트랜지스터(T2)의 드레인 전극에 소스 전극이 연결되는 제1 구동 트랜지스터(T1); 및 일 전극이 입력 전원(VDD)에 연결된 용량 소자의 타 전극에 게이트 전극이 연결되고, 상기 제1 구동 트랜지스터(T1)의 소스 전극에 드레인 전극이 연결되며, 접지에 소스 전극이 연결되는 제2 구동 트랜지스터(T2);를 포함하는 것을 일 특징으로 한다.
