Patent ID: 8466754

Claim:
An oscillator, comprising: an amplifier; a resonator, the resonator being coupled with the amplifier; an amplitude control unit, the amplitude control unit being coupled with the amplifier and being configured for receiving a first oscillating signal from the amplifier, the first oscillating signal being generated via feedback interaction between the amplifier and the resonator and having a first amount of phase noise, the amplitude control unit being further configured for modifying an amplitude of the first oscillating signal and for transmitting the amplitude-modified first oscillating signal to the resonator; a pump drive coupled with the amplitude control unit and the resonator, the pump drive being configured for receiving from the amplitude control unit a signal indicating an amplitude of the amplitude-modified first oscillating signal, the pump drive being further configured for generating a pump signal based upon the indicating signal and supplying the pump signal to the resonator, wherein the pump signal is phase-shifted from the first oscillating signal and configured to activate at the resonance peaks of the resonator to boost power at the resonator when provided to the resonator, and an output buffer coupled with the amplitude control unit.
