Abstract:

An apparatus provides a correction value for an oscillator. At least one parameter sensor measures a system parameter influencing the oscillator. A lookup table determines a cycle adjustment value based on the system parameter. A processor joined to the oscillator implements the cycle adjustment value to correct for oscillator variation. Cycle adjustment values can be computed in both whole cycles and partial cycles through accumulated error thresholding. The parameter sensor can be a temperature sensor, a voltage sensor or both kinds of sensors. The lookup table and processor can have additional terms to account for hysteresis in the oscillator.
