面向ISO18000-6C协议的无源超高频射频识别标签芯片设计 总被引:1,自引:1,他引:0
本文提出了一种面向ISO18000-6C协议的无源超高频射频识别标签芯片设计。为了降低芯片的成本和功耗,本文设计了一种低功耗且不含电阻的稳压电路,一种低功耗且频率精度达到4%的时钟产生电路,以及一种新颖的具有大动态范围的ASK解调电路。本文还阐述了基于门控时钟技术的低功耗数字基带电路设计。该标签芯片的总功耗约为14微瓦,灵敏度达到-9.5dBm,读取距离可达5米。整个标签采用TSMC 0.18um CMOS工艺实现,芯片尺寸为880um880um。 相似文献

This paper presents a new fully integrated wide-range UHF passive RFID tag chip design that is compatible with the ISO18000-6C protocol.In order to reduce the die area,an ultra-low power CMOS voltage regulator without resistors and an area-efficient amplitude shift keying demodulator with a novel adaptive average generator are both adopted.A low power clock generator is designed to guarantee the accuracy of the clock under±4%. As the clock gating technology is employed to reduce the power consumption of the baseband processor,the total power consumption of the tag is about 14μW with a sensitivity of-9.5 dBm.The detection distance can reach about 5 m under 4 W effective isotropic radiated power.The whole tag is fabricated in TSMC 0.18μm CMOS technology and the chip size is 880×880μm~2. 相似文献
