Abstract
There are provided an apparatus for sensing capacitance, a method for sensing capacitance, and a touch screen apparatus. The apparatus for sensing capacitance includes; a driving circuit unit applying driving signals to a first capacitor; an integration circuit unit including a second capacitor and a third capacitor respectively charged by a change in capacitance generated in the first capacitor based on the driving signals to generate a predetermined output voltage and calculating a voltage difference between the output voltage of the second capacitor and the output voltage of the third capacitor; and a control unit determining characteristics of a noise signal based on the voltage difference and controlling the driving signals based on the characteristics of the noise signal.
