Abstract
An oscillator includes a constant current generator configured to generate a constant current by maintaining a predetermined potential difference between both a first end and a second end of a resistor, and an oscillating element configured to output a clock signal corresponding to a charge and discharge cycle of a capacitor based on a bias current corresponding to the constant current.
