  • Apparatus and method for temperature compensation of crystal oscillators
    Patent number: 7649426
    Abstract: An oscillator includes an oscillator circuit and a resonator that produces an output frequency. A temperature compensation circuit is coupled to the oscillator circuit. The temperature compensation circuit stabilizes the output frequency in response to changes in temperature.
