Abstract
An integrated circuit device includes: a first oscillation circuit that oscillates a first resonator to generate a first clock signal with a first clock frequency; a second oscillation circuit that oscillates a second oscillation element to generate a second clock signal with a second clock frequency that is different from the first clock frequency; and a time-to-digital conversion circuit that converts a time into a digital value using the first and second clock signals.
