Review ArticleOpen accessIn the author namesReview of Charge Pump Topologies for Micro Energy Harvesting SystemsMichelle Lim Sern Mi, Md. Shabiul Islam, Jahariah Sampe, Sawal Hamid Md. AliThis paper reviews CMOS based charge pump topologies used within autonomous embedded micro-systems. These charge pump structures have evolved from its simplistic diode-tied, single-branches with major threshold drops to exponential type, dual-branches with sophisticated gate and substrate control for lower voltage operation. Published charge pumps are grouped based on architecture, operation principles and pump optimization techniques with their pros and … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,630 accessesView PDF Cite

Research ArticleOpen accessIn the author namesA Novel Architecture of Maximum Power Point Tracking for Ultra-Low-Power Based Hybrid Energy Harvester in Ubiquitous Devices: A ReviewMichelle Lim Sern Mi, Sawal Hamid Muhammad Ali, Md Shabiul IslamThis research work presents a novel architecture of an Ultra-Low-Power (ULP) based Hybrid Energy Harvester (HEH) consisting of multiple input sources such as kinetic, thermal and solar energy, harvested from passive human power. Having multiple ambient sources mitigates limitations caused by single sources especially for bodily-worn applications; however, this results in impedance mismatch among the different integrated sources. To overcome … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 7,161 accessesView PDF Cite
