A 90nm Passive RFID Tag's Custom Baseband Processor for Subthreshold Operation Below 0.3V

VLSI Implementation of Area and Power Efficient Digital Control Circuit for HF RFID Tag Chip

“…Radio frequency identification (RFID) has been widely used in libraries [1] , pharmaceutical or garment supply chains [2][3][4][5] , Asset management, document tracking, Counterfeit protection for consumer goods, contactless payment [6,7] , sensors [8][9][10] , Location identification [11] and so on. The most common used frequency range can be Low-frequency (LF) (135kHz), High-frequency (HF) (13.56MHz), Ultrahigh-frequency (UHF) (915MHz) [12] and microwave-frequency (2.45GHz). Higher carrier frequency can provide high data rate, yet for some particular systems, e.g.…”
