A physically unclonable device according to an embodiment of the present disclosure comprises: a plurality of inverters disposed on a first path to which a first signal is input; a plurality of inverters disposed on a second path to which a second signal is input; a first MOS capacitor disposed on the first path; and a second MOS capacitor disposed on the second path, wherein a first voltage is applied to a MOS capacitor located on the path corresponding to whichever of the first signal or the second signal arrives later at an output terminal of the first path or an outer terminal of the second path. Accordingly, a physically unclonable device that does not require separate error correction can be achieved.

Physically unclonable device, and signal processing device and image display device having same

Provided are a wireless power transceiver and an image display apparatus including the wireless power transceiver according to the present disclosure. The wireless power transceiver according to an embodiment of the present disclosure comprises a surface electromagnetic (EM) wave transmitter including a first metal layer, a second metal layer, and at least one of a dielectric material formed between the first metal layer and the second metal layer; a surface EM wave receiver including a third metal layer, a fourth metal layer, and at least one of a dielectric material formed between the third metal layer and the fourth metal layer; and a bridge metal plate disposed between the surface EM wave transmitter and the surface EM wave receiver, wherein one end of the signal output terminal is connected to a floating ground. Accordingly, wireless power may be transmitted using surface EM waves.
