Abstract

A system comprises a near-field communication controller (40), a near-field communication antenna (L_ant) electrically coupled to the near-field communication controller (40), and a near-field communication front end circuit coupled between the near-field communication antenna (L_ant) and the near-field communication controller (40), wherein the near-field communication front end circuit comprises a sensing capacitor (C_sense) configured to function as a serial capacitance in a matching circuit (44) of the near-field communication front end circuit, the sensing capacitor (C_sense) is further configured to additionally function as a capacitive proximity sensor, and the near filed communication controller (40) is configured to function as a near-field communication controller and to additionally perform capacitive sensing functionalities.
