Abstract

A near field communication (NFC) reader is disclosed. The NFC reader includes an antenna front-end that includes a low pass filter, a matching circuit and an antenna coil. The NFC reader also includes a NFC controller. The NFC controller includes an oscillator coupled to the antenna front-end and the NFC controller is configured to detect a presence of an object in proximity of the antenna front-end using one or more changes in an output of the oscillator. The antenna front-end creates a tank circuit for the oscillator.
