Abstract
A multi-phase voltage-control oscillator including a first voltage-control oscillator circuit and a second voltage-control oscillator circuit is provided. The second voltage-control oscillator circuit and the first voltage-control oscillator circuit have a plurality of inductors, and the inductors in the second voltage-control oscillator circuit are respectively cross-coupled with the inductors in the first voltage-control oscillator circuit to generate a mutual inductance effect, so as to output a plurality of oscillating signals with different phases.
