Abstract: A near field communication device includes an antenna, a matching circuit connected to the antenna, a clock extraction block that extracts a clock from a signal received by the antenna and outputs the extracted clock, a frequency compensation block that compensates for a frequency of the extracted clock and outputs a compensated clock, and a modulation and amplification block that performs modulation and amplification by using the compensated clock and outputs a transmit signal to the matching circuit. A first extracted clock has a first frequency that is extracted when the transmit signal is not output and a second extracted clock has a second frequency that is extracted when the transmit signal is output, the frequency compensation block compensates for the second frequency of the second extracted clock based on a difference between the first frequency of the first extracted clock and the second frequency of the second extracted clock.

Abstract: A calibrator to process an output signal of an analog digital converter in a wireless communication device, the calibrator comprising a level filter to remove noise from the output signal of the analog digital converter using mask information regulating a signal level; a timing filter to remove pulses from the level-filtered signal that are beyond a reference duty ratio by using timing information; a pattern filter to remove pulses from the timing-filtered signal that are judged to not comprise a reference number of consecutive pulses by using pattern information; and a duty correction circuit to correct a duty of the pattern-filtered signal to improve performance of the wireless communication device by separately performing a filtering operation on noise and a damping component included in a normal signal.

Abstract: A card reader performing a wireless communication with a card includes a first pulse generation unit generating a first detection pulse for detecting the card, a second pulse generation unit generating a plurality of second detection pulses for detecting the card, or a plurality of communication pulses for communicating with the card, and a card detection unit for sensing a card being detected by the first detection pulse or the second detection pulses. In the case that the card is not sensed through the first detection pulse, the second pulse generation unit generates the second detection pulses using the communication pulses and senses the card using the second detection pulses.

Abstract: An internal voltage generation circuit of a smart card to perform fingerprint authentication and a smart card includes a first contact switch, a second contact switch, a switched capacitor converter and a bidirectional switched capacitor converter. The first contact switch selectively switches a contact voltage to a first node based on a first switching enable signal, in a contact mode. The second contact switch selectively switches the contact voltage to a second node based on a second switching enable signal, in the contact mode. The bidirectional switched capacitor converter steps down a first driving voltage of the first node to provide a second voltage to the second node in the contactless mode and either steps down the first driving voltage or boosts a second driving voltage of the second node based on a level of the contact voltage to provide a boosted voltage to the first node in the contact mode.
