Abstract
Embodiments of the present invention provide an oscillator having circuitry that measures the power dissipated in a resonator and circuitry that controls the power delivered to the resonator in response to the measured power. In some embodiments, the circuitry that measures the power dissipated in the resonator comprises circuitry that measures the voltage across the resonator, circuitry that measures the current through the resonator, and circuitry that calculates the power dissipated in the resonator based on the measured voltage and current.
