Piezoelectric resonator with built-in temperature sensor and reference signal generation device

A piezoelectric resonator with a built-in temperature sensor used by being connected to an external electronic device including a temperature compensation circuit, the temperature compensation circuit compensating an oscillation frequency of a piezoelectric vibrating piece in accordance with temperature information detected by a temperature sensor and a preliminarily determined correction formula, the piezoelectric resonator comprising:

• the piezoelectric vibrating piece having a frequency versus temperature characteristic;
• and
• the temperature sensor, wherein
• the temperature sensor has an inter-terminal voltage thereof detected as the temperature information by the connected external electronic device, and
• the piezoelectric resonator comprises a resistor having one end connected to the temperature sensor and another end connected to a predetermined power source of the connected external electronic device, and the resistor has a first resistance value for allowing the inter-terminal voltage to be a planned voltage using the preliminarily determined correction formula, or a second resistance value smaller than the first resistance value or a third resistance value larger than the first resistance value for allowing the inter-terminal voltage to be a correction voltage corresponding to an individual difference of the piezoelectric resonator.
