摘要
为了探索集成太阳能收集作为低功耗系统(如无线传感器节点)的电源，一组基于无源像素架构的能量清除光电二极管用于成像仪，并与使用片上互连的存储电容器一起在0.35 μ m CMOS逻辑工艺中实现。集成的垂直板电容器可以在不限制光学效率的情况下实现密集的能量存储。测量显示，光强为20k LUX时产生的输出功率为225 muW/mm2
To explore integrated solar energy harvesting as a power source for low power systems such as wireless sensor nodes, an array of energy scavenging photodiodes based on a passive-pixel architecture for imagers and have been fabricated together with storage capacitors implemented using on-chip interconnect in a 0.35 mum CMOS logic process. Integrated vertical plate capacitors enable dense energy storage without limiting optical efficiency. Measurements show 225 muW/mm2 output power generated by a light intensity of 20k LUX
