Oscillator device

An oscillator device, comprising:

• a current generating circuit, configured to generate a first current, a second current, a third current and a fourth current;
• a current source, coupled to the current generating circuit, and configured to generate a first reference current according to the first current and the second current, and generate a second reference current according to the third current and the fourth current;
• and
• an oscillator circuit, coupled to the current source, and configured to receive the first reference current and the second reference current and generate an oscillating signal, wherein a temperature coefficient of the oscillator circuit is compensated for by the first reference current and the second reference current;
• wherein at least two of the first current, the second current, the third current and the fourth current are different, and the first reference current is different from the second reference current;
• wherein the first reference current and the second reference current change according to a change of temperature.
