Abstract
Acoustic filtering circuitry includes a piezoelectric layer, a dielectric layer, a plurality of acoustic resonators, and a capacitor. The dielectric layer is over a surface of the piezoelectric layer. The plurality of acoustic resonators each includes a transducer on the surface of the piezoelectric layer such that the transducer is between the piezoelectric layer and the dielectric layer. The capacitor includes a first plate on the surface of the piezoelectric layer such that the first plate is between the piezoelectric layer and the dielectric layer and a second plate over the first plate such that the second plate and the first plate are separated by at least a portion of the dielectric layer.
