    摘要: A Schottky junction diode device having improved performance and a multiple well structure is fabricated in a conventional CMOS process. A substrate including a material doped to a first conductivity type is formed. A first well is disposed over the substrate. The first well includes a material doped differently, such as to a second conductivity type opposite that of the first conductivity type. A second well is disposed within the first well. A region of metal-containing material is disposed in the second well to form a Schottky junction at an interface between the region of metal-containing material and the second well. In one embodiment, a second well contact is disposed in a portion of the second well.

    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 circuit for an RFID tag has at least two RF ports for driving points of the antenna that may correspond to different RF polarizations. The RF ports may be driven by a common modulating signal, or by separate modulating signals. Further, the ports may be coupled and uncoupled together, responsive to a control signal. The control signal may be the same as one or both of the modulating signals.
