An apparatus for generating an oscillating signal including an oscillator configured to generate the oscillating signal, a controller configured to generate a control signal that controls a characteristic (e.g., amplitude or frequency) of the oscillating signal, and a power supply configured to supply power to the oscillator as a function of the control signal. The power supply may be configured to supply power to the oscillator as a function of the amplitude or frequency of the oscillating signal to improve power efficiency.
