    摘要： Process variation-tolerant diodes and diode-connected thin film transistors (TFTs), printed or patterned structures (e.g., circuitry) containing such diodes and TFTs, methods of making the same, and applications of the same for identification tags and sensors are disclosed. A patterned structure comprising a complementary pair of diodes or diode-connected TFTs in series can stabilize the threshold voltage (Vt) of a diode manufactured using printing or laser writing techniques. The present invention advantageously utilizes the separation between the Vt of an NMOS TFT (Vtn) and the Vt of a PMOS TFT (Vtp) to establish and/or improve stability of a forward voltage drop across a printed or laser-written diode. Further applications of the present invention relate to reference voltage generators, voltage clamp circuits, methods of controlling voltages on related or differential signal transmission lines, and RFID and EAS tags and sensors.

    摘要： Multi-mode (e.g., EAS and RFID) tags and methods for making and using the same are disclosed. The tag generally includes an antenna, an electronic article surveillance (EAS) function block coupled to the antenna, and one or more identification function blocks coupled to the antenna in parallel with the EAS function block. The method of reading the tag generally includes the steps of applying an electric field to the tag, detecting the tag when the electric field has a relatively low power, and detecting an identification signal from the tag when the electric field has a relatively high power. The present invention advantageously enables a single tag to be used for both inventory and anti-theft purposes, thereby improving inventory management and control at reduced system and/or “per-article” costs.

    摘要： Printed integrated circuitry and attached antenna and/or inductor for sensors, electronic article surveillance (EAS), radio frequency (RF) and/or RF identification (RFID) tags and devices, and methods for its manufacture. The tag generally includes printed integrated circuitry on one carrier and an antenna and/or inductor on another carrier, the integrated circuitry being electrically coupled to the antenna and/or inductor. The method of manufacture generally includes of printing an integrated circuit having a plurality of first pads on a carrier, forming an antenna and/or inductor having a plurality of second pads on a substrate, and attaching at least two of the first pads of the printed integrated circuit to corresponding second pads of the antenna and/or inductor. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.

    摘要： A method, algorithm, architecture, circuits, and/or systems for EAS, HF, UHF, and RFID designs suitable for multi-tag read applications using TTF anti-collision schemes are disclosed. In one embodiment, a tag for wirelessly communicating with a reader can include: (i) a memory portion with an identifier, the memory having at least one printed layer; and (ii) a circuit for providing a bit string followed by a predetermined silent period, where the bit string is related to the identifier. The tag can include pre-programmed memory bits (e.g., bits the value of which is programmed by printing), or alternatively, memory bits formed by conventional photolithography, but having connections made using printing technology to form the identifier, for example. A unique identifier for each tag or device used in a system under a given set of operating conditions can allow a reader to distinguish between them based on a length and/or value of a bit string, for example. Embodiments of the present invention can advantageously provide a reliable and simplified approach for multi-tag read capable EAS, HF, UHF, and RFID systems using TTF anti-collision schemes.
