摘要：
In an embodiment, a piezoelectric resonator configured for parametric amplification is disclosed. The piezoelectric resonator may include or comprise a piezoelectric member, and first and second resonator electrodes associated with the piezoelectric member and positioned to enable a first electric field to be generated in a first direction. The piezoelectric resonator may also include or comprise a parametric drive electrode associated with the piezoelectric member and positioned to enable a second electric field to be generated in a second direction.
