Design Considerations for the Digital Core of a C1G2 RFID Tag

Behavioral Simulation of ISO 18000-6 Type-C Class 1 Gen2 Protocol for RFID UHF Transponder and its Application as Anti-collision Protocol in Interference Case

“…Generally, the number of states of the FSM and the other included features determine the complexity and functionality of the whole tag [3], [19], [20]. The architecture has eight major sub modules classified into three principal sections [21], [22]: The command detection module is in charge of receiving, decoding and validating the command transmitted by the interrogator.…”

“…It decides what to reply upon receiving a complete data packet from the decoder. This module is in charge to perform the required functions as specified by the functioning of the FSM illustrated in the GEN2 [3], [19], [21], [22]. It contains three main sub modules, (i) Finite State Machine (FSM) to supervise the state transitions of the digital Identification Layer tag architecture, (iii) Session flags to allow more than one reader to independently manage the same population of tags at the same time, and (iii) the slot counter : to copute the slot number at which the Tag will answer.…”
