摘要： Methods and apparatus for temperature control of devices and mechanical resonating structures are described. A mechanical resonating structure may include a heating element and a temperature sensor. The temperature sensor may sense the temperature of the mechanical resonating structure, and the heating element may be adjusted to provide a desired level of heating. Optionally, additional heating elements and/or temperature sensors may be included.

摘要： Circuits for charging capacitors in connection with oscillators are described. The oscillator may include a mechanical resonator. The circuits may include a charging element and a switched capacitor subcircuit to control operation of the charging element, and may be considered a charging circuit in some scenarios. The charging circuits may provide rapid charging of a capacitor to provide a reference voltage to the oscillator.
