Abstract
A near field communication circuit includes an antenna, a circuit logic unit coupled to the antenna, an energy storage coupled to the antenna, and a shunt control circuit, coupled to the antenna, for controlling a first operating voltage provided for the circuit logic unit by the antenna. The circuit logic unit is set up such that in a first mode of operation the circuit logic unit is operated by the first operating voltage provided by the antenna. The circuit logic unit is set up to control the shunt control circuit such that in the first mode of operation at least some of the electric power provided by the antenna is supplied to the energy storage for the purpose of charging same with the electric power.
