Abstract
A circuit device includes an oscillation circuit that includes a variable capacitance circuit and performs an operation of oscillating an oscillation element; and a control unit. The variable capacitance circuit includes a plurality of variable capacitance elements. When an operation mode is a first operation mode, the control unit supplies applied voltages in which at least one thereof is a variable voltage to the plurality of variable capacitance elements, and when the operation mode is a second operation mode, the control unit supplies applied voltages which are all fixed voltages to the plurality of variable capacitance elements.
