More Information
Summary:The invention relates to a sensing circuit with signal compensation, which comprises a first sensing element, a second sensing element and a differential amplification circuit, and the differential amplification circuit generates an output signal through differential compensation according to a common-mode voltage, a first sensing signal and a second sensing signal. Therefore, the noise of the sensing circuit is reduced, and the interference of the display driving signal can be effectively improved. 本发明是有关一种具讯号补偿的感测电路，其包含一第一感测元件、一第二感测元件以及一差动放大电路，该差动放大电路依据一共模电压、一第一感测讯号以及一第二感测讯号经由一差动补偿产生一输出讯号，借此减少感测电路的噪声外，并透过本发明可有效改善显示驱动信号的干扰。
