Publication number: 20240143116Abstract: A touch-sensing circuit and a touch-judging method are provided. The touch-sensing circuit controls the charging process or the discharging process of a sensing capacitor by a charge-discharge control unit. The first comparator and the second comparator are connected to the sensing capacitor to compare whether the voltage level of the sensing capacitor is higher than the preset high voltage or lower than the preset low voltage. The crossing detection unit receives the output pulse of the comparator and samples the first duration before the output pulse has a state transition and the second duration after the output pulse has the state transition. When the second duration is greater than the first duration, a switching signal is sent to the charge-discharge control unit to switch between the charging and discharging processes.Type: ApplicationFiled: June 23, 2023Publication date: May 2, 2024Inventor: Pao-Shu CHANG
