Abstract
Official abstract text for this publication.
Embodiments relate to vertical Hall sensors for use with spinning current techniques. In an embodiment, a symmetric arrangement of two vertical Hall devices is used, in which all sense terminals of the Hall devices are used in all clock phases. Such a configuration can achieve better offset error suppression as compared with conventional solutions.
First claim
Opening claim text (preview).
What is claimed is: 1. A Hall sensor comprising: first and second Hall wells each comprising a plurality of contacts; and first and second amplifiers, wherein: each of the first and second amplifiers is coupled, in a first clock phase, to a first subset of the pluralities of contacts of the first and second Hall wells, wherein the first and second amplifiers are each connected to a contact of the first Hall well and also a contact of the second Hall well, such that the first su…
