摘要： An oscillation circuit is connected to a resonator element (crystal resonator) and oscillates a resonator element to output an oscillation signal. The oscillation circuit includes an amplification element (inverter), and a set of variable capacitive elements having at least two variable capacitive elements, which are connected to an oscillation loop from an output to an input of the amplification element and the capacitance values thereof are controlled with potential differences between reference voltages and a variable control voltage. In each variable capacitive element of a set of variable capacitive elements, the common control voltage is applied to one terminal, and the reference voltage which differs between the variable capacitive elements is input to the other terminal.

摘要： An oscillation circuit includes an amplification circuit that causes a resonator to oscillate, and a variable capacitance circuit whose capacitance value is controlled on the basis of a control voltage. The variable capacitance circuit includes a first variable capacitive element in which an inflection point voltage in a change characteristic of a capacitance value for the control voltage is a first voltage, and a second variable capacitive element in which an inflection point voltage in a change characteristic of a capacitance value for the control voltage is a second voltage which is different from the first voltage. A capacitance value of the first variable capacitive element when the control voltage is the first voltage is different from a capacitance value of the second variable capacitive element when the control voltage is the second voltage.
