Systems and methods for offset reduction in sensor devices and systems

A method of operating a sensor system comprising a plurality of sensor devices arranged proximate one another such that each of the plurality of sensor devices is configured to sense essentially the same condition, each sensor device comprising a plurality of terminals, comprising:

• operating a first sensor device of the plurality of sensor devices in a spinning current mode comprising at least two clock phases by selectively coupling a first terminal of the first sensor device as a supply terminal and a second terminal of the first sensor device as a signal terminal such that, in sequential clock phases, current flows in different directions in at least a portion of the first sensor device and different ones of the plurality of terminals of the first sensor device are the signal terminal;
• determining a partial spinning current output signal of the first sensor device in each of the at least two clock phases of the operating of the first sensor device;
• operating at least a second sensor device of the plurality of sensor devices in the spinning current mode;
• determining a partial spinning current output signal of the at least second sensor device in each of the at least two clock phases of the operating of the at least the second sensor device;
• and
• determining a sensor system output signal based on the partial spinning current output signals of the first sensor device and the at least second sensor device.
