The power transfer efficiency of energy harvesting systems is strongly dependent on the power conditioning circuits, especially rectifiers. The voltage drop across rectifier and its leakage current can drastically influence the efficiency. The hybrid energy harvesters impose even more severe constraints on the rectifier. The low Vth transistors and bulk regulation technique are used in this wor...

Understanding of the complex electrochemical, transport, and phase-change phenomena in Li-S cells requires experimental characterization in tandem with mechanistic modeling. However, existing Li-S models currently contradict some key features of experimental findings, particularly the evolution of cell resistance during discharge. We demonstrate that, by introducing a concentration-dependent el...

Abstract: NMOS-based Integrated Modular Bypass for Use in Solar systems (NIMBUS) is designed as a replacement for the traditional bypass diode, used in common solar panels. Because of the series connection between the individual solar cells, the power output of a photovoltaic (PV) panel will drop disproportionally under partial shading. Currently, this is solved by dividing the PV panel into su...

Local protection elements such as fuses and relays are the first protective mechanism to clear fault isolate affected part of power grid. Although selectivity, speed, sensitivity these primary devices relatively high, they cannot be considered flawless. There is a small percentage events for which experience blinding effects. For scenarios, redundant arrangement can made through backup protecti...

In this paper, we report a novel sample introduction and chemical reaction strategy by drop-by-drop inkjet injection for an electrophoretically mediated microanalysis (EMMA). This method makes it possible to achieve an on-line introduction of reactant solutions by alternately ejecting small plugs, with an overlapping region of the plugs for mixing the reactants by electrophoresis, supporting ch...

This paper describes a novel technique to analyze the effects of supply voltage noise on circuit delay for nanometer VLSI circuits. Scattering parameters are used to analyze the power supply noise and to reduce runtime and memory usage. The interconnections of the power grid are modeled by RLC passive elements, constant voltage and time-varying current sources. A fast and accurate MOS modeling ...
