Problems solved by technology

[0004] There is increasing interest in high-speed (e.g. 1 MHz bandwidth) Hall sensors suitable for use in applications such as lossless current sensing due to, for example, capacitive loading of switches and circuit complexity (e.g., analog to digital ( ADC) / Dual Feedback Loop for Digital-to-Analog (DAC) conversion), while facing inherent limitations

Embodiment Construction

[0012] In this specification, one or more specific details are set forth in order to provide an in-depth understanding of examples of embodiments. Embodiments may be obtained without one or more of the specific details, or with other methods, components, materials, etc. In other instances, known structures, materials, or operations are not shown or described in detail so as not to obscure aspects of the embodiments.

[0013] References to "an embodiment" or "one embodiment" within the framework of this specification are intended to indicate that a particular configuration, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, phrases such as "in an embodiment" or "in one embodiment," which may be present at one or more points in this specification, are not necessarily referring to the same embodiment. Furthermore, particular configurations, structures or characteristics may be combined in any suitable manner in o...

Abstract

The invention provides a Hall sensor and a sensing method, and a corresponding device. A Hall sensor may include a Hall sensing element configured to produce a Hall voltage indicative of a magnetic field when traversed by an electric current, and a first pair of bias electrodes mutually opposed in a first direction across the Hall sensing element. The Hall sensor may include a second pair of bias electrodes mutually opposed in a second direction across the Hall sensing element. The Hall sensor may include a first pair of sensing electrodes mutually opposed in a third direction across the Hall sensing element, and a second pair of sensing electrodes mutually opposed in a fourth direction across the Hall sensing element. The fourth direction may be orthogonal to the third direction, each sensing electrode being between a bias electrode of the first pair and a bias electrode of the second pair.

Description

[0001] related application [0002] This application is based on previously filed co-pending Italian Application No. 102015000039150 filed 28 July 2015, the entire subject matter of which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to sensor devices, and more particularly to Hall sensors and related methods. Background technique [0004] There is increasing interest in high-speed (e.g. 1 MHz bandwidth) Hall sensors suitable for use in applications such as lossless current sensing due to, for example, capacitive loading of switches and circuit complexity (e.g., analog to digital ( ADC) / Dual Feedback Loop for Digital-to-Analog (DAC) conversion) and face inherent limitations. It may be helpful to have an alternative Hall sensor system. Contents of the invention [0005] In general, a Hall sensor may include: a Hall sensing element configured to generate a Hall voltage indicative of a magnetic field when passe...
