Abstract
An integrated circuit device includes a digital signal processing circuit that generates frequency control data by performing a temperature compensation process by a neural network calculation process based on temperature detection data and an amount of change in time of the temperature detection data, and an oscillation signal generation circuit that generates an oscillation signal of a frequency set by the frequency control data using a resonator.
