Abstract
In one embodiment a heating mechanism is provided with an integrated circuit for testing and calibration purposes. During production testing, heating elements may be activated in order to quickly bring an integrated circuit up to operating temperature for temperature testing or calibration. Once the operating test temperature has been reached, the circuit can be quickly and easily tested to show it is operable within the design temperature range and/or to obtain calibration data to correct for temperature drift. Calibration data may be used to create correction data, which may be stored within the integrated circuit. During normal operation, the correction data may be used to compensate for variations in operation due to temperature.
