OSCILLATOR AND CONTROLLING METHOD THEREOF

摘要

An oscillation circuit according to the present invention includes: a temperature change detection unit outputting variable voltage whose size varies in response to a surrounding temperature change; a temperature change correction unit outputting a first output signal whose frequency varies in response to the size of the variable voltage inputted from the temperature change detection unit; and an output signal generation unit generating a second output signal having a constant frequency by using the first output signal inputted from the temperature change correction unit.
