Abstract

Embodiments relate to multi-contact sensor devices and operating methods thereof that can reduce or eliminate offset error. In embodiments, sensor devices can comprise three or more contacts, and multiple such sensor devices can be combined. The sensor devices can comprise Hall sensor devices, such as vertical Hall devices, or other sensor types in embodiments. Operating modes can be implemented for the multi-contact sensor devices which offer significant modifications of and improvements over conventional spinning current principles, including reduced residual offset.

Claims18

Dependent claims

An information storage circuit, comprising:

a first memory portion configured to store information;
a second memory portion configured to store information;
and
an error detection portion comprising:
a reset circuit coupled to the first memory portion, and configured to reset the first memory portion after a predetermined period of time;
a first error detection circuit coupled to the first memory portion, and configured to reset the first memory portion when the first error detection circuit detects an error in the first memory portion;
and
a second error detection circuit coupled to the second memory portion, and configured to reset the second memory portion when the second error detection circuit detects an error in the second memory portion.
