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.
Claims27
An information storage circuit, comprising:
- a first 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 system, comprising:
- an information storage circuit configured to store information for a first predetermined period of time without a power supply;
- and
- a device configured to perform at least a portion of a predefined startup procedure when a last power-down time of the system is greater than a second predetermined period of time.
A method of performing signal processing by a device, the method comprising:
- storing, by the information storage circuit, information during power-down;
- and
- performing at least a portion of a predefined startup procedure of the device when a last power-down time of the device is greater than a predetermined period of time.
