Abstract
A low power oscillator and a method of generating an oscillating signal are disclosed. The low power oscillator includes an oscillating unit for generating a preliminary oscillating signal; an inverter coupled to the oscillating unit in parallel for generating an inverse preliminary oscillating signal fed back to the oscillating unit according to the preliminary oscillating signal, and for generating a first current and a second current according to the preliminary oscillating signal; a first current mirror for generating a first mirror current at an output terminal of the low power oscillator according to the first current; a second current mirror for generating a second mirror current at the output terminal of the low power oscillator according to the second current; and a compensating circuit electrically connected to the inverter for providing a first compensating current and a second compensating current to adjust the first current and the second current, respectively.
