This paper introduces the novel design of a low-voltage low-power voltage rectifier based on bulk-driven (BD) winner-take-all (WTA) circuit. The proposed circuit is able to work as a halfor full-wave rectifier and it is specifically designed for battery-powered implantable and wearable medical devices. The main attractive features of the proposed circuit are topology simplicity, minimal number ...

Germanium nanowire (GeNW)-positioned Schottky solar cell was fabricated by a solution process. A GeNW-containing solution was spread out onto asymmetric metal electrodes to produce a rectifying current flow. Under one-sun illumination, the GeNW-positioned Schottky solar cell yields an open-circuit voltage of 177 mV and a short-circuit current of 19.2 nA. Schottky and ohmic contacts between a si...

four kinds of refrigerant mixtures R22/Rl34a, R22/Rl52a, R22/Rl42b and R22/Rl23, which contain some new halocarbons which are considered to be the alternatives for CFCs, were evaluated in order to realize higher condensing temperature than that using R22 at high temperature operation, and larger heating capacity than that using R22/Rll4 at normal temperature operation. These mixtures were appli...

This paper introduces a new method of electricity generation using Wiegand sensor. The sensor consists magnetic wire and pickup coil wound around it. generates pulse voltage approximately 5 V 20 µs width as an induced in the coil. aim this study is to generate DC from sensor, which expected be used power source self-powered devices battery-less modules. We report on design verification self-osc...

Memristors are promising building blocks for the next-generation memory and neuromorphic computing systems. Most memristors use materials that are incompatible with the silicon dominant complementary metal-oxide-semiconductor technology, and require external selectors in order for large memristor arrays to function properly. Here we demonstrate a fully foundry-compatible, all-silicon-based and ...

A model and simulation software for faults detection, analysis and prediction in multi-layered and single layered printed circuit boards is presented. Fault detection is an intricate process; an engineer must apply wits to search for ways of rectifying and preventing the faults inherent in any electronic device. By application of several electronic paradigms on raw data from test equipments, th...

Neurons communicate through chemical synapses and electrical synapses (gap junctions). Although these two types of synapses often coexist between neurons, little is known about whether they interact, and whether any interactions between them are important to controlling synaptic strength and circuit functions. By studying chemical and electrical synapses between premotor interneurons (AVA) and ...

Electrical coupling in circuits can produce non-intuitive circuit dynamics, as seen in both experimental work from the crustacean stomatogastric ganglion and in computational models inspired by the connectivity in this preparation. Ambiguities in interpreting the results of electrophysiological recordings can arise if sets of pre- or postsynaptic neurons are electrically coupled, or if the elec...
