Abstract
In tablet touch applications, fast sensing is essential to enhance reporting rate and low power consumption is also essential to prolong battery life. To satisfy both essential demands, a fast and energy efficient single-chip touch controller for medium size (7 to 11.6 inch) of capacitive touch screen panels (TSP) is presented. The presented touch controller is designed with fast sensing methods which are proposed to enhance reporting rate and to reduce power consumption. In this paper, the proposed fast sensing methods are described in detail with their implementation and experimental results. The presented touch controller consumes power of 47.50 mA at 10.1 inch TSP, providing the minimum reporting rate of 129 Hz under 10 simultaneous touches.
