摘要： A sensing circuit includes a capacitor array, a comparator, and a processing unit. The comparator compares a detection voltage of each sensing unit with a common voltage of the touch panel to generate a corresponding comparison result. The processing unit generates a corresponding adjustment signal according to the corresponding comparison result. The capacitor array executes a corresponding operation on a present exponent n to generate a corresponding compensation capacitor according to the corresponding adjustment signal, and the capacitor array generates a present compensation capacitor according to a previous compensation capacitor generated by the capacitor array and the corresponding compensation capacitor. Thus, the present invention not only can quickly make a compensation capacitor generated by the capacitor array converge toward capacitor variation generated by the sensing unit, but can also reduce a delay problem of compensating capacitor caused by environmental noise interference.
