Abstract
The invention is a method and apparatus for improving the aging, pressure sensitivity, and acceleration sensitivity of crystal resonators. In one embodiment the invention includes a coplanar two-dimensional compliant mounting structure, wherein the symmetry and compliance of the planar mounting structure reduces the effects of residual static stresses and dynamic vibratory stresses on the vibration sensitivity performance of a crystal resonator. The structural elements include compliance loops that provide relief from the effects associated with manufacturing, thermal and vibration stresses.
