Abstract: A synaptic element performing a multi-level logic operation includes a gate electrode to which a gate voltage pulse is applied, a first electrode, a second electrode, and a multilayer tunnel insulating film in contact with each of the gate electrode, the first electrode, and the second electrode, and disposed such that the gate electrode is spaced apart from the first electrode and the second electrode, and the synaptic element generates a tunneling current flowing from the first electrode to the gate electrode through the multilayer tunnel insulating film based on the gate voltage pulse, the synaptic element operates in one of a turn-on mode, a turn-off mode, and an intermediate mode different from the turn-on mode and the turn-off mode based on the tunneling current, and the synaptic element is trained to generate a drain current in each of the turn-on mode, the turn-off mode, and the intermediate mode.

Abstract: An apparatus and method for estimating a direction of an RF signal are provided. The apparatus includes an antenna unit, a preliminary correction unit, a signal processing unit, a conversion unit, and a signal direction estimation unit. The antenna unit receives an RF signal from at least one antenna. The preliminary correction unit performs preliminary correction depending on whether the at least one antenna is an antenna having directional gain. The signal processing unit generates an analog signal by performing a frequency shift on the RF signal or a signal on which the preliminary correction has been performed. The conversion unit converts the analog signal into a digital sample. The signal direction estimation unit extracts the phase of the antenna from the digital sample, and estimates the direction of the RF signal based on the extracted phase.
