An oscillator is provided and includes a resistance unit, a capacitance unit, a first inverter and a second inverter. The resistance unit is serially connected between a first reference point and a second reference point. The capacitance unit is coupled between the first reference point and an output point, and includes capacitors. One terminal of each of the capacitors is coupled to the output point, and the other terminal of each of the capacitors is coupled to the first reference point or a reference ground according to a control signal. The input terminal of the first inverter is coupled to the first reference point, and the output terminal of the first inverter is coupled to the second reference point. The input terminal of the second inverter is coupled to the output terminal of the first inverter, and the output terminal of the second inverter is coupled to the output point.
