Design and Analysis for 125kHz RFID system

125kHz RFID 시스템의 회로 설계 및 분석

RFID (Radio Frequency Identification) system is applied to identify, locate and track people, cars, animals. Passive RFID system consists of reader and tag. The reader transmits a carrier signal, receives the backscattering signal, performs data processing. The tag is energized by carrier signal that is transmitted from the reader and the information stored in the tag is transmitted back to the reader. In this paper, the design and analysis of the 125kHz RFID system is presented and is confirmed through experiment.
