    Thesis Abstract:

        RFID stands for Radio Frequency Identification, a term that describes any system of identification wherein an electronic device that uses radio frequency or magnetic field variations to communicate is attached to an item. RFID is not a new technology but it has found new applications, with development of other technologies and reduction in cost, from hospitals to highways. RFID system is consists of the tag, which is the identification device attached to the item we want to track, and the reader, which is a device that can recognize the presence of RFID tags and read the information stored on them. The reader can then inform another system about the presence of the tagged items.

        RFID tags work in different range of frequencies such as 125 KHz, 13.56 MHz, 900 MHz, and 2.45 GHz and depending on the way, in which a tag receive its power, they could be divided to passive and active tags. A passive tag receives its required power from the input RF signal which is emitted from the reader. One of the most recent standards in RFID for UHF 900MHz tags has been developed by EPCglobal, Inc., a collaboration between GS1 and industry partners. EPC UHF Generation-2 tags use backscatter coupling and an HDX communication mode, allowing for read ranges of up to 10 meters with optimal orientation of the tag and reader. Reader-to-tag communications are ASK and pulse interval encoded, and tag-to-reader communications are encoded using FSK subcarriers with biphase space or Miller encoding. These tags use a different singulation protocol than the HF tags: the Slotted Random Anti-Collision (SRAC) protocol takes advantage of the faster turnaround time in UHF communications.

        In this thesis the goal is design of a passive-backscatter UHF RFID tag IC in compatibility with the “Class-1 Generation-2 UHF Air Interface Protocol Standard Version 1.0.9”.
