设计，后处理和表征的灰尘大小（0.46毫米（2））的单芯片无线收发器适用于RFID和传感应用。该全集成系统采用GlobalFoundries 45 nm CMOS SOI技术制造，集成了一个微型片上缝隙天线、一个功率收集和管理模块、一个具有反向散射传输功能的调制解调器、一个时钟发生器以及一个数字控制和存储单元。该芯片在0.9 V电源电压下（1V下为114 x 03 BC;W）平均功耗仅为68 x 03 BC;W，由喇叭天线在16 cm以下距离以950 MHz辐射1 W RF功率提供。一种新的后CMOS制造技术被用来释放系统从其处理硅衬底的最终小型化导致最小的体积（
Design, post-processing, and characterization of a dust-size (0.46 mm(2)) single-chip wireless transceiver suitable for RFID and sensing applications are presented. The fully integrated system is fabricated in GlobalFoundries 45-nm CMOS SOI technology and integrates a miniature on-chip slot antenna, a power harvesting and management module, a modem with backscattering transmission, a clock generator and a digital control and memory unit. The chip consumes on average only 68 x03BC;W of power under 0.9-V supply voltage (114 x03BC;W under 1 V) provided by a horn antenna radiating 1 W RF power at 950 MHz at a distance below 16 cm. A novel post-CMOS fabrication technique is used to release the system from its handle silicon substrate for ultimate miniaturization leading to the smallest volume (
