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 first integration circuit unit including a first capacitor charged by a change in capacitance occurring in a sensing electrode; a comparison circuit unit comparing a level of an output signal of the first integration circuit unit with a predetermined reference level; and a noise removal unit including a plurality of switches operating according to an output of the comparison circuit unit, wherein the comparison circuit unit controls an operation of each of the plurality of switches to discharge charges charged in the first capacitor when the level of the output signal of the first integration circuit unit is higher than the reference level.
