NFC receiver and operation method of circuit comprising the NFC receiver
A method of operating a near-field communication (NFC) circuit, the method including: receiving an interference signal and a data signal through an antenna; adjusting magnitudes of the received interference signal and the received data signal; down-converting frequencies of the interference signal and the data signal, the magnitudes of which are adjusted; filtering the data signal by removing the frequency down-converted interference signal; and adjusting a magnitude of the filtered data signal. The adjusting of the magnitudes of the received interference signal and the received data signal may include adjusting the magnitudes of the interference signal and the data signal such that linearity of the data signal is maintained during signal processing performed on the interference signal and the data signal in the down-converting of the frequencies of the interference signal and the data signal, the filtering of the data signal, and the adjusting of the magnitude of the filtered data signal.
