Embodiments included herein are directed towards a ring voltage-controlled oscillator based phase locked loop circuit. Embodiments may include an integral path including a plurality of resistors and a plurality of transistors configured to correct low frequency variations and a proportional path in electrical communication with the integral path, the proportional path including a plurality of transistors and a source degeneration circuit. Embodiments may further include a decoupling capacitor located at a ring voltage-controlled oscillator node in electrical communication with the proportional path, wherein the source degeneration circuit operates to cancel any effect from the ring voltage-controlled oscillator node.
