Abstract: A sensor system is disclosed. The sensor system includes a first sensor path comprising a first sensing element and a second sensing element being connected in series between a first supply terminal and a second supply terminal and an intermediate node connected in between the first supply terminal and the second supply terminal, a second sensor path comprising a third sensing element and a fourth sensing element connected in series between the first supply terminal and the second supply terminal, a first reference node connected in between the first supply terminal and the second supply terminal, and a second reference node connected in between the first supply terminal and the second supply terminal, and a processing unit to receive an input signal from the intermediate node, a first reference signal from the first reference node, and a second reference signal from the second reference node.
