    摘要: A nonvolatile memory cell is constructed using a floating-gate (FG) pFET Readout Transistor (RT) having its source tied to a power source (Vdd) and its drain providing a current which can be sensed to determine a cell state. The gate of the RT provides for charge/information storage. A control capacitor structure (CCS) having terminals coupled to a first voltage source and the FG and a tunneling capacitor structure (TCS) having terminals coupled to a second voltage source and the FG are utilized in each embodiment. The CCS has much more capacitance than the TCS. Manipulation of the voltages applied to the first voltage source and second voltage source (and Vdd) controls an electric field across the CCS and pFET dielectrics and thus Fowler-Nordheim tunneling of electrons onto and off of the FG, thus controlling the charge on the FG and the information stored thereon.

    摘要: Feasibility of a requested action by a reader is predetermined in an RFID tag based on an available tag power level. A pretest that is designed to consume artificially high levels of power is performed and the power level monitored to determine if a preset condition is met. The pretest may include activation of selected components such as a memory and associated support circuitry. If the preset condition is not met, the requested action is aborted and an error message transmitted to the reader.

    摘要: RFID tags are configured to adjust their clock frequency in order to meet predefined limits for reply frequencies to conserve tag power. A deviation of computed tag reply frequency from a reader commanded reply frequency is used to determine an adjustment to the tag clock frequency. The tag clock frequency may be adjusted during backscatter and restored once backscattering is completed.

    摘要: Embodiments of the invention describe a reference current generator circuit having a core circuit that includes a first transistor in a first current path for conduct a first current and a second transistor in a second current path for conduct a second current. The second transistor has a threshold voltage that is different from the threshold voltage of the first transistor by at least 10%. The voltage differential between the first and second transistors generate a voltage across a resistive component coupled in series with the second transistor in the second current path.
