Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 13:
14. The differential sensor system of claim 13, wherein:
in a first configuration, the first, third, fifth, and sixth switches are closed and the second and fourth switches are open, and a voltage difference between a constant input voltage to the resonator and a common voltage to the damping resistor and the second damping resistor electrostatically actuates the transducer and the second transducer and converts a differential thermomechanical noise of the resonator to a differential electromechanical noise; and
in a second configuration, the first, third, fifth, and sixth switches are open and the second and fourth switches are closed, and a pulse input voltage to the resonator produces a differential current correlated to the differential electromechanical noise.
