  7. Abstract:
  8. Radio-Frequency Identification (RFID) in many applications, namely supply chain management; access management; tracking commodity, people, and animals; and storage of medical information, to name but a few, be remembered as the most effective method of gathering information. Accordingly, accurate modeling and optimizing of this technology with attention to its daily development in varied applications, has a significant role. In this regard, some issues – that is – reader location, the number of tags that are controlled by a reader, and data communications of readers with central server, to name but a handful, are challenging and there are attemps to optimize the network in terms of cost, power consumption, and reducing interference effect. In this thesis, there are several attemps based on giving a cellular structure for readers-server communications, compatible with two common RFID standards, to optimize this structure by attending to aforementioned items. The wake-up signal is used to activate the supply (battery) of readers, inasmuch as this given protocol is based on wireless communications. Accordingly, with compatibility of readers and this structure, requisite circuits such as circuits for limiting and rectifying the received signal, are designed and are simulated to provide wake-up signal in 0.18 µm CMOS TSMC
