Abstract:
There is provided a capacitive touch device including a touch panel and a control chip. The touch panel includes a detection electrode configured to form a self-capacitor. The control chip includes an emulation circuit and a subtraction circuit. The emulation circuit is configured to output a reference signal. The subtraction circuit is coupled to the emulation circuit and the detection electrode, subtracts the reference signal outputted by the emulation circuit from a detected signal outputted by the detection electrode to output a differential detected signal, and identifies a touch event according to an amplified differential detected signal so as to improve the touch sensitivity.

Claim (Index 7):
The control chip as claimed in  claim 1 , wherein\n the amplifying circuit comprises an operational amplifier, a feedback resistor and a compensation capacitor, the feedback resistor and the compensation capacitor are connected between a negative input and an output of the operational amplifier, and the input resistor is coupled between the output end of the detection electrode and the negative input of the operational amplifier.
