Abstract
An electronic device is arranged to receive near-field communication signals and comprises: first and second antenna connection terminals and a variable shunt resistance connected between the first and second antenna connection terminals. The device further comprises a peak detector arranged to detect an amplitude of an incoming near-field communication signal across the antenna connection terminals and to produce a peak signal (Vpd) dependent on the amplitude and a comparator arranged to produce an error signal, wherein the error signal is dependent on a difference between the peak signal and a reference signal (Vrefpeak). The device also comprises an integral controller which is arranged to vary the shunt resistance in response to an integral of the error signal. Said configuration is employed for regulating the received voltage and reducing voltage swing.
