기준전압 자동 형성 회로 적용한 13.56㎒ CMOS RFID 리더기 설계

In this paper, 13.56㎒ RFID reader operating at three standards of 14443A/B and 15693 is presented. In Rx mode, the automatic reference voltage circuit technic is implemented and automatically operated for all three 13.56㎒ RFID standards. In TX mode, the open drain type amplifiers with inductor loading are adapted for high efficiency and high current driving capacity. This reader chip was fabricated in a 0.18㎛ CMOS technology. The die area is 1.5㎜×1.5㎜
