Abstract

In one embodiment, an apparatus is provided that includes a first circuit (120) configured and arranged to provide a modulated carrier signal in response to a signal provided from the antenna (104). The modulated carrier signal conveys data using peaks or amplitudes of the carrier signal. A second circuit (130) is configured to rectify (132) the modulated carrier signal and integrate (134) the rectified signal in response to a first clock signal. A third circuit (140) is coupled to an output of the second circuit and is configured to sample the integrated signal values and provide therefrom a sample-based approximation of the modulated carrier signal.
