  • Patent number: 9413432
    Abstract: Provided is a near field wireless communication apparatus that uses magnetic coupling and a method for operation of the apparatus, in which the magnetic coupling is used to transmit data or clock information with low power and high efficiency. A pulse generator of the near field wireless communication apparatus generates a pulse signal corresponding to transmission digital data to be transmitted. When the transmission digital data is “1,” the near field wireless communication apparatus modulates the data into the pulse signal and transmits the pulse signal. When the data is “0,” the near field wireless communication apparatus does not output the pulse.
