Abstract
Piezoelectric resonator structures and circuits therefor are provided to p the energy available for vibrational deformation in a resonator, between the driving electrodes of the resonator structure. Field trapping electrodes are disposed to enclosed the driving electrodes in the resonator structures which are arranged in circuits to derive electric fields between the field trapping electrodes in an opposite direction to that of an electric field between the driving electrodes.
