Abstract
There is described a method of operating an NFC device, the method comprising: determining a resonance frequency of a matching network of the NFC device; modulating, by a modulator, a carrier signal received from an external reader, resulting in a modulated carrier signal; controlling, using a controller, a transmission of the modulated carrier signal to the external reader; and transmitting, by a transmitter driver, said modulated carrier signal, said transmitter driver having at least one configurable setting that influences a damping behavior of the transmitted modulated carrier signal, wherein, during a modulation phase of the NFC device, the controller selects and applies the at least one configurable setting based on the determined resonance frequency such that a clock synchronization window is widened. Furthermore, a corresponding NFC device is described.
