1. A voltage controlled oscillator (VCO) comprising:

  • a negative resistance circuit; and

    a hybrid resonator comprising;

    a first resonance branch having a first resonance frequency, the first resonance branch comprising at least a first inductor and a first capacitor coupled in series;

    a second resonance branch coupled in parallel to the first resonance branch, the second resonance branch comprising at least a second inductor and a second capacitor coupled in series, the second resonance branch having a second resonance frequency, the first resonance frequency being lower than the second resonance frequency; and

    a third resonance branch coupled between the negative resistance circuit and the parallel first and second resonance branches, the third resonance branch comprising at least a third inductor and a third capacitor coupled in series.
