Abstract
A circuit for an NFC chip is described herein. According to one exemplary configuration, the circuit comprises an antenna for near field communication, an antenna resonant circuit which has an adjustable resonant frequency, a temperature sensor and a controller circuit coupled to the temperature sensor. The controller circuit is designed to change the resonant frequency of the antenna resonant circuit according to a temperature sensor signal provided by the temperature sensor.
