Abstract: A calibration device, method and electronic device using the same provided by embodiments of the present disclosure only need to measure frequency values of two temperatures, then calculate frequency drift rates of various configuration combinations, and select the configuration combination with the smallest frequency drift rate to set configuration values of a trimming module. Thus, the test time can be reduced. In one embodiment, a simple heating device can be directly disposed on the chip package structure of the electronic device, so it is not necessary to use an external heating device for heating, and the environmental space required for placing the external heating device can be reduced.
