(English Abstract)
This paper describes a low-power high-performance analog front-end block for UHF(860¢¦960MHz) band RFID tag chips. It satisfies ISO/IEC 18000-6 type C(EPCgolbal class1. generation2.) and includes a memory block for test. For reducing power consumption, it operates with an internally generated power supply of 1V. An ASK demodulator using a current-mode schmitt trigger is proposed and designed. The proposed demodulator has an error rate as low as 0.014%. It is designed using a 0.18um CMOS technology. The simulation results show that the designed circuit can operate properly with an input as low as 0.2Vpeak and consumes 2.63§Ë. The chip size is 0.12§±
