ABSTRACT:
A multi-phase voltage-control oscillator including a first voltage-control oscillator circuit and a second voltage-control oscillator circuit is provided. The first voltage-control oscillator circuit includes a first LC tank and a first inductor assembly unit. The second voltage-control oscillator circuit includes a second LC tank and a second inductor assembly unit. A mutual inductance effect is generated between the inductors of the first voltage-control oscillator and the inductors of the second voltage-control oscillator.
