摘要： Timing oscillators as well as related methods and devices are described. A timing oscillator may include a mechanical resonating structure with major elements and minor elements coupled to the major element. The timing oscillator can generate stable signals with low phase noise at very high frequencies which allows a timing oscillator to be used effectively in a number of devices including computers and mobile phones for time and data synchronization purposes. The signal generated by the timing oscillator can be tuned using a driver circuit and a compensation circuit.

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.
