Abstract:
The present invention relates to a voltage controlled oscillator and phase locked loop comprising the same for compensating a noise of a power voltage. According to an embodiment of the present invention, a voltage controlled oscillator may comprise: an oscillator comprising a plurality of inverters connected as a ring form for generating a plurality of signals having different phases with each other, and a plurality of feed forward circuits formed between the inverters; and a controller for controlling the inverter and feed forward circuit based on a detected noise by detecting a noise of a power voltage.
