A power transmission circuit includes a first transmission transistor, a second transmission transistor, and a first control circuit. A first terminal of the first transmission transistor is used as a power input terminal of the power transmission circuit. A second terminal of the first transmission transistor is coupled to a first node. A control terminal of the first transmission transistor is coupled to a control node. A first terminal of the second transmission transistor is used as a power output terminal of the power transmission circuit. A second terminal of the second transmission transistor is coupled to the first node. When a voltage of the power output terminal is greater than or equal to a voltage of the power input terminal, the first control circuit outputs a first voltage to the control node, to turn off the first transmission transistor and the second transmission transistor.

Electronic device and power transmission circuit of same

An antenna structure and an electronic device using the same are provided. The antenna structure includes an antenna body and a washer body. The antenna body includes an annular metal sheet. The washer body is connected to one side of the annular metal sheet. The washer body has a screw hole. The annular metal sheet surrounds the washer body, and the annular metal sheet extends upward from the washer body.
