Patent ID: 8193869

Claim:
A device comprising: a drive voltage source to provide a drive signal; a phase inversion circuit coupled to the drive voltage source and having an in-phase node and an inversion node; and a resonator array including first and second sets of resonators, each resonator of which is configured for selective activation and coupled to the drive voltage source for excitation of the resonator via the drive signal; wherein each resonator in the first set is coupled to the in-phase node along a respective one of a plurality of parallel in-phase paths, and wherein each resonator in the second set is coupled to the inversion node along a respective one of a plurality of parallel inversion paths; and wherein the first and second sets of resonators include a matching number of multiple resonators such that each resonator in the first set is paired with a companion resonator in the second set to offset a feedthrough capacitance of each resonator.
