ABSTRACT:
A microelectromechanical (MEMs) resonator includes a concave bulk acoustic resonator (CBAR). One embodiment of a CBAR includes a substrate and a resonator body suspended over the substrate by a pair of fixed supports that attach to first and second opposing ends of the resonator body. The resonator body has a first concave-shaped side extending between the first and second ends of the resonator body and a second concave-shaped side extending opposite the first concave-shaped side. The resonator body may be configured to have a minimum spacing of λ/2 between the first and second concave-shaped sides, where λ is a wavelength associated with a resonant frequency of said resonator body.
