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： A memory device includes a mechanical element that exhibits distinct bistable states under amplitude modulation. The states are dynamically bistable or multi-stable with the application of a drive signal of a given frequency. The natural resonance of the element in conjunction with a hysteretic effect produces distinct states over a specific frequency range. Devices with multiple elements that respond to different frequency ranges provided on a common contact are formed with improved density. The devices may be excited and read with magnetomotive, capacitive, piezoelectric and/or optical methods. The devices may be planar oriented or out of plane oriented to permit three dimensional memory structures. DC biases may be used to shift frequency responses to permit an alternate method for differentiating states of the element.

摘要： Mechanical resonating structures are described, as well as related devices and methods. The mechanical resonating structures may have a compensating structure for compensating temperature variations. The compensating structure may have multiple layers, one of which may have a stiffness that increases with increasing temperature and one of which may have a stiffness that decreases with increases in temperature.

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.
