Abstract

Disclosed are apparatus and methodology for providing approaches to remove or reduce thermal drift of the magnetic sensitivity of Hall sensor devices, to improve the stability of resulting signals of interest. Samples of a particular signal or signals of interest having improved stability make for advantageous use in conjunction with electricity meters. At the same time, associated designs and related components have greater simplicity, for reduced complexity in implementation. Among alternative embodiments, a gating structure selected of various present alternative designs may be used to partially cover, to an intentionally selected degree, an active area of a Hall sensor, so that a zero-drift supply current value may likewise be selected so as to satisfy other criteria which may be applicable to use of the Hall sensor. In other alternative embodiments, a gate structure is used which fully covers the Hall sensor active area, but a gate- control technique is practiced which is based on combined use with an external, relatively high resistance voltage-divider circuitry arrangement, again for eliminating temperature-based drift of the magnetic sensitivity of the Hall sensor arrangement, regardless of the end use to which such Hall sensor is applied.
