Abstract
An adaptive demodulator for a contactless device, including a rectifier configured to rectify a voltage which is dependent on a signal received by the contactless device, and a voltage regulator coupled to the rectifier and configured to adjust the voltage to be within a voltage window.
Claims25
An adaptive demodulator for a contactless device, comprising:
- a rectifier configured to rectify a voltage which is dependent on a carrier signal received by the contactless device;
- and
- a voltage regulator configured to adjust the rectified voltage to be within a voltage window, and to generate a data stream based on the rectified voltage,
- wherein the data stream represents data modulated with the carrier signal.
