The present invention is a voltage controlled oscillator (voltage-controlled oscillator; VCO) of a high-performance relates to a technique for reducing the phase noise (phase-noise) in the, according to the present invention, a terminal current source to improve the phase noise performance of the VCO removed when and increases the oscillation output voltage and the phase noise is worsened by reducing the load impedance of the LC tank, using the harmonic tuning method solve the problem of the conventional voltage controlled oscillator (VCO), there was a problem that consumes a lot of chip area to, conventional parallel LC resonators (parallel LC resonator) instead of the cross-coupled series resonant LC tank (cross-coupled series resonant LC tank) the provided by the phase noise reduction to be so configured that the new structure of the series LC resonant circuit as the having low phase noise is provided a CMOS voltage controlled oscillator and a method of designing such an oscillator structure.
