  • Patent number: 12321798
    Abstract: An RFID IC may operate at a relatively low clock frequency while impedance matching to an antenna is being tuned to increase the amount of power that the IC can extract from an incident RF wave. A tuning circuit tunes the impedance matching by adjusting a variable impedance coupling the IC and the antenna. The IC may power-up with a low clock frequency or reduce its current clock frequency to a lower clock frequency prior to tuning or during the tuning process, and may increase its clock frequency upon completion of tuning or during the tuning process.

  • Patent number: 9607191
    Abstract: Data stored in nonvolatile memory on a Radio Frequency Identification (RFID) tag integrated circuit may have a “margin” associated with how strongly the data is written to the memory. Upon receiving a wireless margin read command, the RFID IC determines whether the margin for one of more data values stored in memory exceeds a margin threshold. The IC may determine the margin by applying bias voltages or currents to the memory cells storing the data values. If the determined margin does not exceed the margin threshold, the IC may respond with an error code.

  • Patent number: 9349090
    Abstract: A tuning circuit in an RFID tag may be used to match antenna and integrated circuit (IC) impedances to maximize the efficiency of IC power extraction from an incident RF wave. The tuning circuit, which requires less power to operate than the IC, adjusts a variable impedance to improve the impedance matching between the IC and the tag antenna and thereby increase the IC power extraction efficiency. The IC may begin operating according to a protocol when it extracts sufficient power from the RF wave or when an optimal impedance matching and power transfer is achieved.

  • Patent number: 9087282
    Abstract: An RFID tag tuning circuit may be capable of adjusting the impedance matching between an RFID integrated circuit (IC) and an antenna on an RFID tag to increase the amount of power that the IC can extract from an incident RF wave. The tuning circuit switches a variable impedance coupling the antenna and the IC between several different impedance settings, where each impedance setting differs from an adjacent impedance setting by a respective impedance step size and at least one impedance step size has a different value than another impedance step size. The tuning circuit may switch the variable impedance by incrementing through a counter, decrementing through the counter, or performing some search algorithm. The tuning circuit may also initialize the variable impedance based on a default impedance setting or a random impedance setting derived from a random counter.

    Abstract: A Radio Frequency Identification (RFID) tag integrated circuit (IC) includes a power rectifier component. The rectifier component includes a first current path formed by a first rectifying element, a second rectifying element, and a pump node coupled to the first and second rectifying elements. The first and second rectifying elements are coupled to a first phase of a radio frequency (RF) waveform while the pump node is coupled to a second phase of the RF waveform. The rectifier component also includes at least one biasing element coupled to the pump node and configured such that its terminal voltages vary with phases and amplitudes similar to that of the second phase of the RF waveform.
