Near field communication device
A near field communication device includes an amplifier that amplifies a signal received through an antenna and outputs the signal as an amplified receive signal, a gain control block that adjusts a gain of the amplifier based on a level of a noise included in the amplified receive signal during a noise reception sequence, and a data determination block that determines a noise threshold voltage based on the level of the noise of the amplified receive signal after the gain is completely adjusted and determines data from the amplified receive signal by using the noise threshold voltage.
