Abstract
A touch sensing device applied to an electronic device including a side portion having a cover that is nonconductive, and a frame that is conductive, includes: a first touch sensing portion including a first sensing electrode and a first sensing inductor disposed inside the cover and electrically connected to each other, wherein, in response to a touch applied through the cover by a human body, a capacitance is varied by the first touch sensing portion according to parasitic capacitance generated between the first sensing electrode and the human body according to the touch applied through the cover; and a reference sensing portion including a reference coil disposed inside the side portion and configured to provide reference inductance of the reference coil that is constant, regardless of a touch applied through the frame.
