METHODS AND APPARATUS FOR CALIBRATION AND TEMPERATURE COMPENSATION OF OSCILLATORS HAVING MECHANICAL RESONATORS
摘要
<p>Methods and apparatus for calibration and temperature compensation of oscillators having mechanical resonators are described. The method(s) may involve measuring the frequency of the oscillator at multiple discrete temperatures and adjusting compensation circuitry of the oscillator at the various temperatures. The compensation circuitry may include multiple programmable elements which may independently adjust the frequency behavior of the oscillator at a respective temperature. Thus, adjustment of the frequency behavior of the oscillator at one temperature may not alter the frequency behavior at a second temperature.</p>
