Abstract: An electronic device includes a power supply, such as a battery, configured to supply a power supply voltage. The device further includes a controllable voltage converter circuit configured to generate a control voltage based on the power supply voltage. A near-field communication device is included that has at least one antenna configured to emit an electromagnetic field having a power that is controllable by the control voltage. The electronic device further includes a temperature measuring device configured to measure a temperature. The controllable voltage converter circuit is configured to modify a value of the control voltage based on the measured temperature.
