Abstract
A touch device, comprising a touch circuit and a processor. The processor comprises a first sensing circuit and a second sensing circuit. The first sensing circuit is coupled to a detection capacitor of the touch circuit, and is configured to detect a capacitance change of the detection capacitor according to a first reference value. The second sensing circuit is coupled to the detection capacitor of the touch circuit, and determines an equivalent capacitance value of the detection capacitor to generate a second reference value. The second sensing circuit detects the capacitance change of the detection capacitor according to the second reference value. The first sensing circuit detects the capacitance change of the detection capacitor in multiple detection periods, the second sensing circuit determines the equivalent capacitance value of the detection capacitor in multiple calibration periods, and the calibration periods and the detection periods are staggered.
