    摘要： This disclosure provides implementations of filters and filter topologies, circuits, structures, devices, apparatus, systems, and related processes. In one aspect, a device includes one or more LC resonant circuit stages. In some implementations, each LC stage includes an inductor and a capacitor. Each LC stage also has a corresponding resonant frequency. The one or more LC stages are arranged to produce an unmodified passband over a range of frequencies having a corresponding bandwidth. One or more microelectromechanical systems (MEMS) resonators are arranged with the one or more LC stages. The one or more MEMS resonators are arranged with the one or more LC stages so as to modify characteristics of the unmodified passband such that the hybrid filter produces a modified passband having a modified bandwidth and one or more other modified band characteristics.

    摘要： This disclosure provides implementations of electromechanical systems (EMS) piezoelectric resonator structures, transformers, devices, apparatus, systems, and related processes. In one aspect, a piezoelectric resonator structure includes a first conductive electrode layer, a second conductive electrode layer, and a piezoelectric layer arranged between the first and second conductive layers. In some implementations, the surface of the piezoelectric layer adjacent to the first conductive layer is separated from the first conductive layer by a first gap, and the surface of the piezoelectric layer adjacent to the second conductive layer is separated from the second conductive layer by a second gap. In some implementations, the resonator structure further includes an encapsulation layer arranged over the second conductive layer and providing physical support to the second conductive layer.
