38.1: A Low-Power Fast Readout Circuit using a Dual-Mode Sensing Algorithm for Medium-Size Capacitive Touch Screen Panels

A new readout circuit architecture for capacitive touch screen panels (TSPs) is introduced to enhance the reporting rate and to improve the signal to noise ratio (SNR) with low power consumption. The proposed Dual‐Mode Sensing (DMS) method finds the actual touch spots without feedback from the TSP t...
