<p>There is provided an oscillator capable of lowering the power supply voltage without degrading the phase noise, while employing the conventional circuit configuration. According to one aspect of the present invention, there is provided an oscillator comprising: an oscillation circuit (1); a bias generation circuit (2) for generating a bias signal to drive the oscillation circuit (1) ; and a booster circuit (3) for boosting a power supply voltage to generate a boosted voltage for driving the bias generation circuit. In addition, the oscillation circuit (1), the bias generation circuit (2), and the booster circuit (3) are provided in a single IC chip (10), and the booster circuit (3) may receive the power supply voltage VDD from the power supply arranged at the exterior of the IC chip (10).</p> |
