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

摘要

A temperature information generation circuit includes a temperature sensor (a first temperature detection section), a high-sensitivity temperature sensor (one or plural second temperature detection sections) having higher sensitivity than that of the temperature sensor, an output selection circuit, and a control section. The output selection circuit and the control section select a detection signal of the high-sensitivity temperature sensor upon supply of a power supply voltage, and then perform switching so as to select a detection signal of the temperature sensor at a predetermined timing.
