Abstract
Several circuits and methods for field-based communication are provided. In an embodiment, a field-based communication circuit includes a receiver circuit, a detection circuit and a control circuit. The receiver circuit is configured to receive a field input signal from a field source. The detection circuit includes a voltage detection circuit and a current detection circuit configured to detect a voltage signal and a current signal, respectively associated with the field input signal. The control circuit is configured to trigger a selection of one of the voltage detection circuit and the current detection circuit based on a detection of a signal magnitude of one of the voltage signal and the current signal relative to at least a first predetermined threshold level, wherein the selection of one of the voltage detection circuit and the current detection circuit facilitates a demodulation of one of the voltage signal and the current signal.
