1. An integrated circuit comprising:

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

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

    an output circuit adapted to provide an output interface for signal communication.
