  • Temperature compensated crystal oscillator
    Patent number: 10790831
    Abstract: A temperature compensated crystal oscillator implements temperature compensation by generating and applying a temperature compensation signal via a function having a plateau region and a higher slope region, where a horizontal position of the higher slope region, a slope value in the higher slope region, and a function value change magnitude over the higher slope region are adjustable.

  • Acceleration tolerant piezoelectric resonator
    Patent number: 7247978
    Abstract: The invention relates to piezoelectric resonators. An interposer element is used between a resonating plate and the resonator package to provide improved (i.e. reduced) acceleration sensitivity. The interposer element is preferably of similar thermal expansion characteristics to the resonating plate. Electrical connection to the resonating plate from the exterior of the package is preferably provided via the interposer element.
