Abstract
A load-modulation detection component for an inductive coupling reader device. The load-modulation receiver device is arranged to receive an antenna voltage signal representative of a voltage across an antenna of the inductive coupling reader device and output at least one load-modulated signal. The load-modulation detection component comprises a down-converter component arranged to mix the antenna voltage signal with a down-conversion signal to generate a down-converted signal, a series capacitive component coupled in series between an output of the down-converter component and an output of the load-modulation receiver, and a switched capacitor resistor circuit coupled between the output of the load-modulation receiver and a first reference voltage.
