1. An integrated circuit, the integrated circuit comprising:

  • a reference resonator comprising an inductor and a capacitor, the reference resonator to provide a first reference signal having a first frequency;

    a voltage controller to provide a control voltage;

    a first plurality of controlled reactance modules coupled to the reference resonator and to the voltage controller, each controlled reactance module of the first plurality of controlled reactance modules to provide a corresponding reactance in response to the control voltage to maintain the first frequency substantially constant in a first operating mode; and

    a processor operatively coupled to the reference resonator.
