摘要

在本文中,我们提出了一种用于超低功耗自主传感器应用的停电和限电不敏感能量收集ASIC。它利用射频或直流电源输入为片上和片外设备提供稳压。集成了电压限制器,用于过电压保护。由于ASIC交替使用两个稳压器,因此使用了一种启动方法来切换操作模式。ASIC采用0.18 μm CMOS工艺实现。它能够使用宽范围的输入直流电压(0.8…2)V在-40…85°C)或输入交流电源低至-14 dBm。

Energy harvesting ASIC for autonomous sensors
In this paper, we present a blackout and brownout insensitive energy harvesting ASIC for ultra-low power autonomous sensor applications. It utilizes both RF or DC power inputs to deliver a regulated voltage for on-chip and off-chip devices. A voltage limiter has been integrated for overvoltage protection. As the ASIC utilizes two regulators alternately, a kick-start method has been used for switching the operation mode. The ASIC is implemented in a 0.18 μm CMOS process. It is able to use a wide range of input DC voltages (0.8...2 V at -40...85 °C) or input AC powers down to -14 dBm.
