SYSTEMS AND METHODS FOR FREQUENCY COMPENSATION OF REAL-TIME-CLOCK SYSTEMS
First Claim
1. A method for temperature-dependent frequency compensation, the method comprising:
- determining a first frequency compensation as a first function of temperature using one or more crystal oscillators;
processing information associated with the first frequency compensation as the first function of temperature; and
determining a second frequency compensation for a crystal oscillator as a second function of temperature based on at least information associated with the first frequency compensation as the first function of temperature;
wherein;
the one or more crystal oscillators do not include the crystal oscillator; and
the first frequency compensation as the first function of temperature is different from the second frequency compensation as the second function of temperature.

Abstract
Method and system for temperature-dependent frequency compensation. For example, the method for temperature-dependent frequency compensation includes determining a first frequency compensation as a first function of temperature using one or more crystal oscillators, processing information associated with the first frequency compensation as the first function of temperature, and determining a second frequency compensation for a crystal oscillator as a second function of temperature based on at least information associated with the first frequency compensation as the first function of temperature. The one or more crystal oscillators do not include the crystal oscillator, and the first frequency compensation as the first function of temperature is different from the second frequency compensation as the second function of temperature.
