TEMPERATURE-COMPENSATED OSCILLATOR AND DEVICE INCLUDING THE SAME

摘要

A temperature-compensated oscillator and a device including the same include an oscillation unit configured to generate an oscillation signal using an operating current and an operating voltage, a bias circuit configured to control the operating current so that a frequency of the oscillation signal increases as a temperature increases, and a voltage generation unit configured to generate the operating voltage that varies with the temperature.
