I am just wondering if there is any research about AMS-circuits performances to meet the requirements of an energy harvesting-sensor requirement. What are the investigated performances and to meet which goal or to staisfy which constraint?
IMEC made first true energy-harvesting industrial device (tire pressure sensor) back in 2012.
You can also see my paper:
The Availability and Statistical Properties of Ambient Light for Energy-Harvesting for Wearable Sensor Nodes
Also, the same research (not published) yielded estimation of 80 uW/kg harvestable energy of wearable sensor from vibration.
Basicaly, for sensor node of reasonable size, average power consumption must be 20-200 uW. In particular, SOI CMOS is the most suitable for AMS microchips.
For ADC, dominant architecture for energy-harvesting is charge-reuse ADCs, especially SAR architecture is popular. Current-based ADCs has simply too high power consumption
