Abstract
A circuit device includes an oscillation circuit that generates an oscillation signal using a resonator, a temperature detection circuit that outputs temperature detection data, a temperature compensation circuit, and a temperature detection rate control circuit. The temperature compensation circuit performs temperature compensation on an oscillation frequency of the oscillation signal based on the temperature detection data. The temperature detection rate control circuit controls a temperature detection rate at which the temperature detection circuit executes temperature detection. At this time, the temperature detection rate control circuit controls the temperature detection rate based on a variation in the temperature detection data.
