摘要： A readout circuit for use with a Wheatstone bridge sensor. At least some of the example embodiments are methods including: driving an excitation signal in parallel through a first set of sensor elements of a Wheatstone bridge sensor and refraining from driving the excitation signal through a second set of sensor elements of the Wheatstone bridge sensor; measuring response of the first set of sensor elements, the measuring response of the first set of sensor elements creates a first measurement; and then driving the excitation signal in parallel through the second set of sensor elements of the Wheatstone bridge and refraining from driving the excitation signal through the first set of sensor elements; and measuring response of the second set of sensor elements, the measuring response of the second set of sensor elements creates a second measurement.
