This paper presents an RF identification (RFID) system with a fully integrated transponder. To enable the on-chip integration of the tag's antenna, it is suggested to employ near-field coupling at high-frequency ranges, i.e., the UHF band. The RFID system including the reader and key blocks of the transponder is designed and fabricated in a standard CMOS 0.18-mum process. The system operates at 900...
This paper presents an RFID system with fully integrated transponder. The transmit path of the reader as well as key blocks of the tag is designed and fabricated in standard CMOS 0.18 mum process. The system operates at 900 MHz with the coverage range of more than 0.4 cm. The tag's antenna is integrated on chip without using any special process. The reader employs a coil switching technique to increase...
