摘要： In a temperature sensor, especially in a temperature sensor using a resonator, based on a frequency of one oscillator circuit (resonator), frequencies of the other one or more oscillator circuits (resonators) are measured, and frequency-temperature characteristics of a plurality of resonators are synthesized in order to realize an accurate temperature sensor which does not require an accurate frequency reference regardless of a temperature change, and has a linear characteristic and a wide measurable temperature range. Also, two oscillator circuits have two resonators respectively with quadratic characteristics in which quadratic coefficients are the same and linear characteristics are different from each other, and a difference between oscillation frequencies of both oscillator circuits is obtained.

摘要： A temperature compensated crystal oscillator is mounted to a board. A quartz resonator includes a quartz chip that generates an oscillation frequency. A resistive element is formed on the quartz chip. A temperature sensor is located closer to the board than the quartz resonator. The compensation part compensates for a change in the oscillation frequency generated by the quartz resonator based on a value of a current flowing in the resistive element and an output of the temperature sensor.
