Abstract
(EN)
A circuit and an electronic device. The circuit comprises: an antenna (11), a touch-control chip (12) and a communication chip (13), wherein the antenna (11) forms a detection electrode, and the detection electrode is electrically connected to the touch-control chip (12) and the communication chip (13), respectively; and when a finger touches the antenna (11), the capacitance of the antenna (11) changes, the touch-control chip (12) detects a change in transmission data of the detection electrode, and the touch-control chip (12) triggers the electronic device to execute an instruction corresponding to a touch-control operation. Compared with the prior art, the circuit and the electronic device can realize two functions, the functions of an antenna and touch control, by means of the antenna (11), so that the functions of touch control and an antenna are effectively integrated, the circuit occupies a smaller volume, and a touch-control operation is more sensitive.
