Drain Current Modulation of a Single Drain MOSFET by Lorentz Force for Magnetic Sensing Application

This paper reports a detailed analysis of the drain current modulation of a single-drain normal-gate n channel metal-oxide semiconductor field effect transistor (n-MOSFET) under an on-chip magnetic field. A single-drain n-MOSFET has been fabricated and placed in the center of a square-shaped metal loop which generates the on-chip magnetic field. The proposed device designed is much smaller in s...

Magnetic fields in electrochemistry: The Lorentz force. A mini-review

Some recent work on the flow induced by uniform or non-uniform magnetic fields acting on currents in an electrochemical cell is reviewed. The effects include modifying the structure and texture of electrodeposits including their chirality, controlling hydrogen bubble release, inducing microfluidic flow and influencing nucleation. Much of this depends on micro-magnetohydrodynamic flow, on a scal...

Single-borehole imaging using gravity gradiometer data

We present a feasibility study for interpretation of gravity gradient surveys in a single borehole using both an analytic and inverse-based approach. We analytically solve for distance and direction angles to a point source using the components of the gravity gradient tensor from a set of observations in a single borehole. We then generalize this approach to include the response due to a prisma...

Force-rebalanced Lorentz force magnetometer based on a micromachined oscillator

Single-chip computers with microelectromechanical systems-based magnetic memory „invited..

This article describes an approach for implementing a complete computer system ~CPU, RAM, I/O, and nonvolatile mass memory! on a single integrated-circuit substrate ~a chip!—hence, the name ‘‘single-chip computer.’’ The approach presented combines advances in the field of microelectromechanical systems ~MEMS! and micromagnetics with traditional low-cost very-large-scale integrated circuit style...
