NVM arrays include rows and columns of NVM cells comprising a floating gate and a four transistor storage element. Supply voltage for selected storage elements is turned off during a programming and an erase mode. Isolation transistors for each NVM cell or for each row of NVM cells may be used to control the supply voltage.

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.

摘要:
Systems and methods to determine timebase and timing (i.e., time sync) of received signals in RFID systems. Multiple matched filters corresponding to multiple timebases are used to receive the preambles of signals received from RFID tags. The multiple matched filters define a range of expected timebases of the received signals. The matched filter with the maximum output signal peak is used to derive the timebase and timing of the received signal. Viterbi techniques can be used in determining the timebase and timing to incorporate a portion of the data signal in addition to the preamble. Reconfigurable matched filters can be used so that after a preliminary timebase is determined as described above, the matched filters can be reconfigured to define a new smaller range centered about the preliminary timebase. This allows the timebase to be determined with finer resolution when another preamble portion is received.

NVM arrays include rows and columns of NVM cells comprising a floating gate, dual transistor, inverter storage element. Supply voltage for selected storage elements is turned off during a programming and an erase mode. Isolation transistors for each NVM cell or for each row of NVM cells may be used to control the supply voltage.
