Abstract
Embodiments of a mixer of a Near field communication (NFC) receiver device and a method for operating a mixer of an NFC receiver device are disclosed. In an embodiment, a mixer of an NFC receiver device includes an input unit from which an input signal is received, a sample and hold circuit configured to sample the input signal and to store electrical charge based on the sampled input signal in order to generate a differential output signal, a control unit configured to switch the sample and hold circuit between different operational modes based on whether the input signal is a single-ended input signal or a differential input signal, and a differential output unit from which the differential output signal is output. Other embodiments are also described.
