Abstract
An integrated circuit frequency generator is disclosed. In some embodiments, the frequency generator comprises an electronic oscillator configured to generate an oscillator frequency, calibration circuitry configured to periodically calibrate the electronic oscillator with respect to a reference frequency at a first calibration frequency when at a steady state temperature and at a second calibration frequency when at a transient temperature, and circuitry configured to generate an output frequency from the oscillator frequency.
