Abstract
An electronic device includes one or more processors, a memory storing instructions, and a user interface including at least one touch button, a capacitor coupled with the at least one touch button, and a switch configured to charge the capacitor and to discharge the capacitor. The instructions, when executed by the one or more processors individually or collectively, cause the electronic device to spread an operating frequency into a plurality of spread frequencies within a frequency range, determine, based on the plurality of spread frequencies, whether to at least one of charge the capacitor or discharge the capacitor by controlling the switch to at least one of turn on or turn off, measure a charging time of the capacitor, according to the controlling of the switch, and determine whether a touch input on the at least one touch button occurs, based on the measured charging time.
