Abstract
An integrated circuit device includes a first temperature sensor, a second temperature sensor, an A/D conversion circuit that performs A/D conversion on first and second temperature detection voltages from the first and second temperature sensors and outputs first and second temperature detection data, a digital signal processing circuit that generates frequency control data by performing a temperature compensation process by a neural network calculation process based on the first and second 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.
