Power electronic circuits are moving toward higher switching frequencies, exploiting the capabilities of novel devices, so as to shrink dimension passive components. This trend demands sensors able operate at such high frequencies. article aims demonstrate broadband capability a fully integrated CMOS current sensor based on X-Hall approach and configured in mode, by alleviating impact stray cap...

Integrated CMOS Hall sensors have been widely used to measure magnetic fields. However, they are difficult to work with in a low magnetic field environment due to their low sensitivity and large offset. This paper describes a highly sensitive digital Hall sensor fabricated in 0.18 μm high voltage CMOS technology for low field applications. The sensor consists of a switched cross-shaped Hall pla...

Out-of-equilibrium systems can host phenomena that transcend the usual restrictions of equilibrium systems. Here, we unveil how out-of-equilibrium states, prepared via a quantum quench in a two-band system, can exhibit a nonzero Hall-type current-a remnant Hall response-even when the instantaneous Hamiltonian is time reversal symmetric (in contrast to equilibrium Hall currents). Interestingly, ...

3D printers are tools utilized to create real 3D samples using the 3D files within your computer. The first feasibility and idea of such tools dates back to 1950. The very first sketch of 3D printers was presented in 1980s called "Rapid Prototyping" and the first sample was developed by Charles Hall and it was recorded with the name of the same scientist. But the current 3D printers were fi...

The current interest in ion thrusters for near-Earth and deep-space missions has occurred because of long-term development efforts yielding an understanding of the physical phenomena involved in thruster operation and hardware that is suited to a wide range of missions. Features of state-of-the-art thrusters are described in terms of the various physical processes that occur within them. Tradeo...

We investigated the Integer Quantum Hall Effect (IQHE) using an inductive method. The following conclusions can be derived from our study: (i) when the Fermi energy is located between Landau levels the only extended states at the Fermi energy are located at the physical edges of the sample. (ii) the extended states located at the bulk of the sample below the Fermi energy are capable of carrying...

Two thirds of US households hold bank type credit cards, and most of them revolve high-interest card debt. Standard models cannot account for the observed co-existence of such debt with (i) substantial asset accumulation by retirement age, and (ii) substantial holdings of low-rate liquid assets. Hyperbolic discounting can resolve the former but not the second puzzle (Laibson, et al., 2000). Ber...

Development and Characterization of High-Efficiency, High-Specific Impulse Xenon Hall Thrusters by Richard Robert Hofer Chair: Associate Professor Alec D. Gallimore This dissertation presents research aimed at extending the efficient operation of 1600 s specific impulse Hall thruster technology to the 2000-3000 s range. While recent studies of commercially developed Hall thrusters demonstrated ...

We have measured the Hall effect on recently synthesized single crystals of the quasi-one-dimensional organic conductor TTF-TCNQ (tetrathiafulvalene-tetracyanoquinodimethane), a well known charge transfer complex that has two kinds of conductive stacks: the donor (TTF) and the acceptor (TCNQ) chains. The measurements were performed in the temperature interval 30 K < T < 300 K and for several di...

This paper studies the effects of the covering layers on the performance of a cross-like Hall plate. Three different structures of a cross-like Hall plate in various sizes are designed and analyzed. The Hall plate sensitivity and offset are characterized using a self-built measurement system. The effect of the P-type region over the active area on the current-related sensitivity is studied for ...
