摘要： A device or system that incorporates teachings of the present disclosure may include, for example, a resonant structure having a plate, a mass and a set of electrodes. The plate can have an extensional mode at a frequency when excited. The set of electrodes can be used to measure an acceleration of the mass when the acceleration of the mass changes the frequency of the plate. Other embodiments are disclosed.

摘要： In one embodiment, an apparatus includes a resonant structure having a plate, a drive electrode and a sense electrode. The resonant structure defines an axis substantially orthogonal to a plane defined by the plate when the resonant structure is not excited. The plate is formed from a piezoelectric material. The drive electrode is configured to excite the resonant structure, and the sense electrode is configured to sense a signal in response to rotation of the resonant structure about the axis.

摘要： Multi-port devices having multiple electrical ports are described, as are related methods. Some of the multi-port devices may have two input ports and two output ports, and may be driven differentially, in a single-ended mode, in a single-ended to differential mode, or in a differential to single-ended mode. The multi-port devices may include one or more transducers coupled to the electrical ports.

摘要： Mechanical resonating structures and related methods are described. The mechanical resonating structures may provide improved efficiency over conventional resonating structures. Some of the structures have lengths and widths and are designed to vibrate in a direction approximately parallel to either the length or width. They may have boundaries bounding the length and width dimensions, which may substantially align with nodes or anti-nodes of vibration.

摘要： Apparatus and methods of connecting mechanical resonating structures to a body are described. Multi-element anchors may include a flexible portion that flexes when the mechanical resonating structure vibrates. The flexible portion may have a length related to the resonance frequency of the mechanical resonating structures. Some of the multi-element anchors include elements that are oriented perpendicularly to each other. MEMS incorporating such structures are also described.
