Wireless Sensor Network (WSN) is one of the emerging research domains which have posed numerous unique challenges to researchers. The low cost MEMS and low processing capability with ultra low power consumption and low range wireless communication makes it lucrative for being exploited in abundance in future. The inbuilt limitation of energy in the sensor nodes which demanded every functionalit...
With technology scaling, power supply and threshold voltage continue to decrease to satisfy high performance and low power requirements. In the past, subthreshold CMOS circuits have been inadequate for high performance applications, but have been used in applications that require ultra low power dissipation. Many applications including medical and wireless applications, require ultra low power ...
Wireless medical body-area networks are used to connect sensor nodes that monitor vital parameters. The radio consumes a large portion of the sensor energy budget, and hence its power dissipation should be minimized. The low-noise amplifier (LNA) is an important component of the receiver, and must guarantee low-noise amplification and impedance matching. In this work, an ultra-low-voltage ultra...
New instrumentation which is sensitive to the detection of ultra low energy (<100eV) X-rays [1,2], promises new analysis capability for the SEM; so called ‘Soft X-ray Microanalysis’. Only those soft X-rays that are generated close to the surface of the sample escape and therefore they offer potential for surface and higher spatial resolution analysis. The detectability of very low energy K, L a...
Title of Document: AN ULTRA-LOW POWER VOLTAGE REGULATOR SYSTEM FOR WIRELESS SENSOR NETWORKS POWERED BY ENERGY HARVESTING Chao Wang, Doctor of Philosophy, 2014 Directed By: Professor Martin Peckerar Department of Electrical and Computer Engineering A DC-DC converter is an important power management module as it converts one DC voltage level to another suitable for powering a desired electronic s...
The article describes the research program towards an experiment to observe coherent scattering between neutrinos and the nucleus at the power reactor. The motivations of studying this process are surveyed. In particular, a threshold of 100-200 eV has been achieved with an ultra-low-energy germanium detector prototype. This detection capability at low energy can also be adapted for searches of ...
Noise immunity and low-energy computing have become limiting factors in the semiconductor roadmap as transistor feature sizes shrink. The subject of our study is the probabilistic switch, implemented in the complementary metal–oxide– semiconductor (CMOS) domain, referred to as a probabilistic CMOS (PCMOS) switch, whose behavior is rendered probabilistic by noise. In conducting this study, we ar...
