There is provided an oscillator providing a clock signal having a uniform duty ratio by generating a toggled voltage by charging and discharging a capacitor with a voltage irrespective of a temperature from a band gap circuit. The oscillator includes: a band gap circuit providing a band gap reference voltage having a pre-set voltage level; a voltage-current conversion unit converting the band gap reference voltage from the band gap circuit into a current; a charging/discharging unit charging/discharging the converted current and providing a triangle wave signal; and a T flip-flop logically operating a pulse signal according to a maximum value of the triangle wave signal from the charging/discharging unit and providing a clock signal having a fixed duty. |
