Abstract
A circuit device includes an oscillation signal generation circuit that generates an oscillation signal having an oscillation frequency, the oscillation frequency being a frequency set by using frequency control data, and a processor that is configured to perform a signal process on input frequency control data, and. The processor is configured to acquire the frequency control data from which an environmental change component is removed of the environmental change component and an aging change component by using environmental change component information, and perform aging correction on the basis of the frequency control data from which the environmental change component is removed.
