Abstract: This paper introduced the principle of mutual capacitance touch screen and touch control integrated circuit, then made a design and implementation of noise suppression module which is embedded in the touch control integrated circuit. This module could increase the touch control integrated circuit’s noise suppression ability, and further increased the mutual capacitance touch screen’s signal to noise ratio.
Key words: microelectronics; integrated circuit design; mutual capacitance touch screen; touch control integrated circuit; signal to noise ratio
