ABSTRACT:
A piezoelectric resonator (10) includes a single crystal elongated plate (12) having a transverse extensional mode of oscillation. Two sets of split electrodes (20,22,30,32) are provided on the surfaces (14,16) of the plate (12) to define two acoustically coupled oscillating regions (24,26) therebetween. The oscillating regions (24,26) present a similar inductance and have similar performance to allow the use of the resonator (10) in a double-ended electrical transformer circuit (100). An AC source (112) drives non-opposing top and bottom electrodes of the resonator (110). The remaining electrodes are coupled with shunt capacitors to provide two resonant LC circuits with the resonator (110) so as to provide a voltage gain for driving a load.
