Reducing charge redistribution loss for supercapacitor-operated energy harvesting wireless sensor nodes
ENSsys '14: Proceedings of the 2nd International Workshop on Energy Neutral Sensing SystemsPages 31–36https://doi.org/10.1145/2675683.2675691With increasing demand of long term applications, supercapacitors have been widely chosen as energy storage devices for energy harvesting aware wireless sensor networks( WSNs) due to their long charging-discharging life cycles. However, few studies have ...

Analysis on capacitor mismatch and parasitic capacitors effect of improved segmented-capacitor array in SAR ADC
IITA'09: Proceedings of the 3rd international conference on Intelligent information technology applicationPages 280–283This paper presents an analysis on capacitor mismatch and parasitic capacitors effect of the improved segmented-capacitor array to alleviate the limitation of mismatching performance and avoid a non-binary-weighted coupling capacitor. Both the matching ...
