| description | Disclosed is technology for sensing a touch input with a method to alternatively perform feedback connection of two feedback capacitors connected between output terminals of two output drivers and inversion input terminals of two operation transconductance amplifiers by changing an interconnection state between the two output drivers and the two operation transconductance amplifiers. Accordingly, the present invention can reduce deviation of an output value between sensing channels generated by different input offsets generated in a plurality of operational amplifiers.
두 개의 연산 트랜스컨덕턴스 증폭기와 두 개의 출력 드라이버의 상호연결 상태를 변화시킴으로써, 상기 두 개의 연산 트랜스컨덕턴스 증폭의 반전 입력단자와 상기 두 개의 출력 드라이버의 출력단자 사이에 연결된 두 개의 피드백 커패시터를 번갈아가면서 피드백 연결하는 방식으로 터치입력을 감지하는 기술을 공개한다. |
