Patent
Acoustic resonator structure comprising a bridge
John Choy,Chris Feng,Phil Nikkel +2 more
TL;DR: An acoustic resonator comprises a first electrode, a second electrode and a piezoelectric layer disposed between the first and second electrodes as mentioned in this paper, and a reflective element disposed beneath the first electrode.
Patent
Acoustic resonator structure having an electrode with a cantilevered portion
John Choy,Chris Feng,Phil Nikkel +2 more
TL;DR: An acoustic resonator comprises a first electrode and second electrode comprising a plurality of sides, and at least one of the sides of the second electrode comprises a cantilevered portion.
Patent
Film bulk acoustic resonator (FBAR) devices with temperature compensation
John D. Larson,John Choy,Donald Lee,Kevin J. Grannen,Feng Hongjun,Carrie A. Rogers,Urupattur C. Sridharan +6 more
TL;DR: The temperature-compensated film bulk acoustic resonator (FBAR) as discussed by the authors is a novel type of resonator, which consists of opposed planar electrodes and a piezoelectric element between the electrodes.
Patent
Transducer devices having different frequencies based on layer thicknesses and method of fabricating the same
David Martin,John Choy +1 more
TL;DR: In this article, a transducer array on a common substrate includes a membrane and first and second transducers, each of which is formed on the common substrate, and includes a lower layer and an upper layer.
Patent
Bulk acoustic wave resonator having piezoelectric layer with multiple dopants
TL;DR: In this paper, a piezoelectric material doped with multiple rare earth elements was used to improve the piezelectric properties of the layer of a BAW resonator.
