Abstract

Several Hall sensor configurations have been integrated in CMOS technology and analyzed in terms of offset at room temperature and offset drift. We looked for the best geometry that would minimize the offset and its drift. The targeted specification was 30 T for offset at room temperature and 0.3 T/C for the drift. The measurement setup developed allows a clean, reliable and fast analysis of a high number of the same type of cell, located on different positions on the chip. Geometrical correction factor maximization was also performed for small sensing contacts Hall structures in order to ensure maximum sensitivity. © 2011 IEEE.

Froude number

In continuum mechanics, the Froude number (Fr, after William Froude, ˈfruːd) is a dimensionless number defined as the ratio of the flow inertia to the external field (the latter in many applications simply due to gravity). The Froude number is based on the speed–length ratio which he defined as: where u is the local flow velocity, g is the local external field, and L is a characteristic length. The Froude number has some analogy with the Mach number.

Strouhal number

In dimensional analysis, the Strouhal number (St, or sometimes Sr to avoid the conflict with the Stanton number) is a dimensionless number describing oscillating flow mechanisms. The parameter is named after Vincenc Strouhal, a Czech physicist who experimented in 1878 with wires experiencing vortex shedding and singing in the wind. The Strouhal number is an integral part of the fundamentals of fluid mechanics.

Least-squares spectral analysis

Least-squares spectral analysis (LSSA) is a method of estimating a frequency spectrum based on a least-squares fit of sinusoids to data samples, similar to Fourier analysis. Fourier analysis, the most used spectral method in science, generally boosts long-periodic noise in the long and gapped records; LSSA mitigates such problems. Unlike in Fourier analysis, data need not be equally spaced to use LSSA.
