Claim Text:
1. A method comprising: receiving, at first and second input terminals, first and second input voltages, respectively, wherein the first and second input voltages are about 180° relative to each other; responsive to receiving, at a rectifying circuit assembly in electrical communication with the first and second input terminals, the first and second input voltages, maintaining the direction of the first and second input voltages and doubling the first and second input voltages; measuring, by a Wheatstone bridge, an applied physical parameter; outputting, by the Wheatstone bridge and to a capacitor, and to first and second operational amplifiers, first and second signals substantially indicative of the physical parameter; reducing, by the capacitor, a DC component of the first and second signals; amplifying, by the first and second operational amplifiers, the first and second signals; adjusting, by a gain resistor in electrical communication with the first and second operational amplifiers, a differential output between first and second output voltages that correspond to the first and second signals output from the Wheatstone bridge, respectively; and outputting, by a first output terminal and a second output terminal, the first and second output voltages, respectively.
