Abstract
A voltage-controlled oscillator robust against power supply includes: a regulating unit configured to maintain a virtual power supply of a VCO core circuit in a stable condition with regard to a reference voltage; and a power supply removal unit including second transistors configured to correspond to respective first transistors of the regulating unit, the power supply removal unit being configured to remove power noise of the virtual power supply by using negative feedback through a closed-circuit loop formed by each of the first and second transistors.
