ABSTRACT:
Apparatus, systems, and methods may include providing a power-on reset function to many types of receiving circuitry, including radio frequency identification (RFID) tag processing circuitry. Thus, the power-on reset function may be realized by applying a supply voltage to a power-on reset circuit coupled to RFID tag processing circuitry. Operations may include sensing a first current substantially independent of the supply voltage, sensing a second current substantially dependent on the supply voltage, and indicating a power-on reset condition based on a comparison between the first current and the second current. Additional apparatus, systems, and methods are disclosed.
