Abstract
A radio frequency identification (RFID) tag includes a power harvesting circuit that operates generate power for the RFID tag from a continuous wave of a radio frequency (RF) signal. The RFID tag further includes a self-tuning circuit that is tuned based on a capacitance setting, where the capacitance setting is indicative of a power level of the power. The RFID tag further includes a processing module operably coupled to the tuning circuit, where the processing module operates to generate the capacitance setting to obtain a desired power level for the power. In an example, the processing module further generates an adjustment signal in response to a change in an impedance of an antenna coupled to the RFID tag, and generates a digital value representative of the adjustment signal.
