Abstract
A touch sensing device includes: an oscillation circuit including a sensing inductor disposed inside a touch member, a part of a cover of an electronic device, and generating an oscillation signal according to whether a touch has occurred through the touch member; a signal processor converting the oscillation signal into a digital sensing signal; a reference signal generator updating a reference signal based on the digital sensing signal; and a signal detector outputting a detection signal by detecting whether a touch has occurred through the touch member, using the reference signal and the digital sensing signal.
