    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: Electromechanical systems dilation mode resonator (DMR) structures are disclosed. The DMR includes a first electrode layer, a second electrode layer, and a piezoelectric layer formed of a piezoelectric material. The piezoelectric layer has dimensions including a lateral distance (D), in a plane of an X axis and a Y axis perpendicular to the X axis, and a thickness (T), along a Z axis perpendicular to the X axis and the Y axis. A numerical ratio of the thickness and the lateral distance, T/D, is configured to provide a mode of vibration of the piezoelectric layer with displacement along the Z axis and along the plane of the X axis and the Y axis responsive to a signal provided to one or more of the electrodes. Ladder filter circuits can be constructed with DMRs as series and/or shunt elements, and the resonators can have spiral configurations.
