Abstract
A mechanical resonator-based oscillator comprises an input signal generator configured to output an input signal, a mechanical resonator comprising a body configured to vibrate according to the input signal and to output a vibration signal, a phase detector configured to detect a relative phase of the vibration signal with respect to the input signal, and a frequency synthesizer configured to produce a temperature-insensitive oscillation output based on the relative phase. The input signal generator comprises an adder configured to add the drive amplitude to the tone amplitude to produce an amplified pilot tone, and a mixer configured to modulate the amplified pilot tone with the drive frequency to produce the input signal. The oscillator further comprises a temperature compensator determines a multiplier to scale the relative phase, wherein the frequency synthesizer performs a scale operation on the vibration signal by the multiplier to produce the temperature-insensitive oscillation output.
