TEMPERATURE INFORMATION GENERATION CIRCUIT, OSCILLATOR, ELECTRONIC APPARATUS, TEMPERATURE COMPENSATION SYSTEM, AND TEMPERATURE COMPENSATION METHOD FOR ELECTRONIC COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a temperature information generation circuit capable of achieving exact temperature compensation of an electronic component immediately after starting.SOLUTION: A temperature information generation circuit 200 includes: a temperature sensor 60 (a first temperature detector); a high-sensitivity temperature sensor 70 (a second temperature detector) with higher detection sensitivity than that of the temperature sensor 60; an output selection circuit 80; and a controller 90. The output selection circuit 80 and the controller 90, once a power voltage is supplied, select a detection signal of the high-sensitivity temperature sensor 70 and switch so that a detection signal of the temperature sensor 60 is selected at predetermined timing.
