    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 systems, methods, and apparatus for high capacitance density metal-insulator-metal capacitors. In one aspect, an apparatus may include a first base metal layer on a first side of a substrate. A first polymer layer may be disposed on the first base metal layer and on the first side of the substrate. The first polymer layer may define a first plurality of vias though the first polymer layer, the first plurality of vias exposing portions of the first base metal layer. A first electrode layer may be disposed on the first polymer layer. The first electrode layer may contact the portions of the first base metal layer. A first dielectric layer may be disposed on the first electrode layer. A second electrode layer may be disposed on the first dielectric layer. The first dielectric layer may electrically isolate the first electrode layer from the second electrode layer.
