P-178: Design of On-Panel Readout Circuit for Touch Panel Application
نویسندگان
چکیده
An on-panel readout circuit for touch panel application has been designed and fabricated in a 3-μm low temperature poly-silicon (LTPS) technology. The minimum detectable voltage difference of the proposed circuit is 30 mV. The switch-capacitor technique is applied to amplify the voltage difference from capacitance change due to touch panel. The corrected double-sampling (CDS) technique is also employed to reduce the offset originated from process variation.
