摘要
An oscillation circuit includes a terminal XO which is connected to one end of a resonator, a terminal XI which is connected to the other end of the resonator, an oscillation unit which is electrically connected to the terminal XO and the terminal XI, a control voltage generation circuit, and a switch. The oscillation unit includes a variable capacitive element having one end which is connected to the terminal XO or the terminal XI. The switch controls electrical connection between the other end of the variable capacitive element and an output terminal of the control voltage generation circuit.
