摘要
提出了一种无线供电无源传感器的方案，该方案将接收到的超出灵敏度水平的额外功率存储起来，然后用于提高无线传感器的灵敏度。采用0.13 μ m CMOS技术设计并制作了原型芯片。测量结果表明，上述储能机制将无线传感器的灵敏度从900MHz时的- 19.5dBm提高到- 29dBm，在2.4GHz时的- 15.4dBm提高到- 26.5dBm。
A wirelessly-powered passive RF CMOS transponder with dynamic energy storage and sensitivity enhancement
A scheme for a wirelessly-powered passive sensor is presented in which the extra received power beyond the sensitivity level is stored and later used to enhance the sensitivity of the wireless sensor. A prototype chip has been designed and fabricated in a 0.13µm CMOS technology. The measurement results show that the aforementioned energy storage mechanism improves the sensitivity of the wireless sensor from −19.5dBm to −29dBm at 900MHz and from −15.4dBm to −26.5dBm at 2.4GHz.
