Abstract
Disclosed is a touch sensing system, including a detected capacitor Cm. A transmitting electrode and a receiving electrode of a sensor are arranged at two ends of the detected capacitor Cm, and one end of the detected capacitor Cm corresponding to the receiving electrode is connected to a modulation module via a GM module. An excitation signal is input from the transmitting electrode. The GM module converts a charge transferred to the receiving electrode into a current and outputs same to the modulation module, and the modulation module performs integration and modulation according to the current to obtain an output parameter characterizing the detected capacitor Cm. Provided is a touch sensing system to reduce chip area and power consumption and improve the reliability of touch sensing.
