Variable capacitance circuit, oscillator circuit, vibratory device, electronic apparatus, moving object, and method of manufacturing vibratory device
A variable capacitance circuit includes a plurality of variable capacitance elements (varicaps) each having the capacitance value controlled in accordance with the inter-terminal voltage applied between the terminals of the variable capacitance element and connected in parallel to each other, has the combined capacitance value of the plurality of variable capacitance elements variable taking a predetermined capacitance value as a base, sets the inter-terminal voltage of at least one of the plurality of variable capacitance elements to a first voltage as a variable voltage, and sets the inter-terminal voltage of the rest of the plurality of variable capacitance elements to a second voltage as a stationary voltage.
