Abstract
A circuit device according to the embodiment includes an oscillation circuit, a current supply circuit, a counter circuit, and a calculation circuit. An oscillation frequency of the oscillation circuit changes according to a supply current. The current supply circuit supplies, to the oscillation circuit, a first current that changes according to a detection target voltage. The counter circuit performs a count process of counting an output signal of the oscillation circuit in a given period. The calculation circuit performs a voltage calculation process of calculating detection voltage data corresponding to the detection target voltage based on a first count value obtained in the count process in a state in which the first current is supplied to the oscillation circuit.
