Abstract
A touch sensing circuit is applied to a touch panel to generate a sensing signal. The touch panel includes a sensing device. The touch sensing circuit includes: an interference signal detecting circuit, configured to detect an interference signal of the touch panel to generate an interference signal detection result; a control signal generating unit, configured to generate a control signal according to the interference signal detection result; and a sensed value analyzing circuit, configured to charge the sensing device in a first time interval and to discharge the sensing device in a second time interval, and to generate the sensing signal according to a sensed value of the sensing device. A length of one of the first time interval and the second time interval changes according to a control signal.
