Abstract
An integrated circuit device includes an oscillation circuit that generates an oscillation signal by causing a resonator to oscillate, a temperature compensation circuit that performs temperature compensation of an oscillation frequency of the oscillation circuit, an output circuit that outputs a clock signal based on the oscillation signal, a first regulator that generates a first regulated power supply voltage based on a power supply voltage and supplies the first regulated power supply voltage to the temperature compensation circuit, and a second regulator that generates a second regulated power supply voltage based on the power supply voltage and supplies the second regulated power supply voltage to the output circuit.
