    摘要: Embodiments of RFID tag circuits and methods are described, which include a chip having a clock circuit operable to generate a clock signal having different frequencies, and one or more components operable to work at the different frequencies. In addition to a regular frequency, at least one higher frequency is possible, which is enabled in situations where a reader is known to be close to the chip. The proximity ensures that the chip generates reliably more power, which enables its operation at the higher speed.

    摘要: RFID tags are assembled through affixing an antenna to an integrated circuit (IC) by forming one or more capacitors coupling the antenna and the IC with the dielectric material of the capacitor(s) including a non-conductive covering layer of the IC, a non-conductive covering layer of the antenna such as an oxide layer, and/or an additionally formed dielectric layer. Top and bottom plates of the capacitor(s) are formed by the antenna traces and one or more patches on a top surface of the IC.
