1. An integrated circuit device comprising:

  • a first digital controlled oscillator, wherein the first digital controlled oscillator comprises;

    a first set of inductors, each one of the first set of inductors having a first inductance;

    a second set of inductors, each one of the second set of inductors having a second inductance different from the first inductance, wherein individual ones of the first set of inductors are in series with individual ones of the second set of inductors;

    a switched capacitor array connected between the first set of inductors and the second set of inductors;

    a first active feedback device connected to the first set of inductors;

    a second active feedback device connected to the first set of inductors; and

    a capacitor connected between a first inductor of the first set of inductors and a second inductor of the first set of inductors, the capacitor having a constant capacitance; and

    a second digital controlled oscillator coupled to the first digital controlled oscillator.
