1. A voltage-controlled oscillator comprising:

  • a first phase shifter and a second phase shifter each having an inductor-capacitor resonator circuit, wherein the respective resonant frequencies of said first and second phase shifters are different; and

    an interpolator having an inductor-capacitor resonator circuit, wherein the resonant frequency of said interpolator is set between the respective resonant frequencies of said first and second phase shifters;

    wherein, signals generated by said first and second phase shifters are selectively combined by said interpolator using a control signal.
