TEMPERATURE STABILISED OSCILLATOR

摘要

There is provided a system for automatically integrally calibrating an oscillator (10) and/or a phase-locked loop (30, 32, 34) to achieve frequency accuracy and stability in a synthesized radio, particularly a radio where the temperature of an oscillator can be set. Temperature calibration is performed by integrally determining the present optimal operating temperature for the oscillator and integrally resetting the temperature of the oscillator to that optimal temperature. Thus, frequency vs. temperature stability is achieved; frequency calibration may follow.
