摘要： 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.

摘要： An Integrated Circuit (IC) for an RFID tag contains at least two demodulators, each having an RF input port configured to receive and demodulate an RF input signal, with one or more of the RF inputs being a differential signal, and with at least two of the RF input ports electrically isolated from each other. The RFID IC contains two or more envelope detectors for recovering analog modulation envelope signals from the RF signals, and one or more slicers to convert the modulation envelopes to at least one digital signal. The analog signals from the two envelope detectors may be first combined, then converted to a digital signal. Alternatively, the analog modulation envelopes may be first converted to digital signals then combined in a digital combiner. Alternatively, the analog modulation envelopes may be converted to separate digital signals without being combined.

摘要： An Integrated Circuit (IC) for an RFID tag includes two electrically isolated antenna ports for connecting to two antennas, with each antenna port configured to operate at a different frequency range and/or with a different communications protocol. In some embodiments a rectifier coupled to one of the antenna ports is operable to extract energy from an electromagnetic field in a first frequency range, and a demodulator coupled to the other antenna port is operable to demodulate symbols according to an RFID protocol in a second frequency range. In some embodiments the frequency ranges are disjoint, intersecting, or one is a proper subset of the other. In some embodiments each port is coupled to its own rectifier and/or its own modulator and/or its own demodulator. In some embodiments an RFID tag includes the IC and two antennas, each operable in one of the two frequency ranges.

摘要： RFID tags have an on-chip antenna and an off-chip antenna. One of the antennas can become uncoupled if the proper signal is received, while the other antenna may still operate. The uncoupled antenna can be the larger one, for example the off-chip antenna. Then the tag can then be read only by the smaller antenna, which effectively reduces the range of the RFID tag, but without disabling it entirely.

摘要： A system and method for generating a rectified signal in a RFID tag. An alternating signal is received by the RFID tag, and a first phase of the alternating signal is coupled to a gate and to a first non-controlling terminal of a first switching transistor. The non-controlling terminal of the first switching transistor is one of a source and a drain of the first switching transistor. A first bias voltage is applied between the first non-controlling terminal and the gate of the first switching transistor and a rectified voltage is received between the first non-controlling terminal and a second non-controlling terminal of the first switching transistor.
