Abstract:
A Radio Frequency (RF) device such as a Radio Frequency Identification (RFID) tag according to one embodiment includes a Digital to Analog Converter (DAC) for generating a reference signal based on a stored digital comparison criteria value, and a mechanism for comparing an incoming signal to the reference signal. The device performs an action such as backscattering based on the comparison. Additional systems and methods are also disclosed.
