Embodiments relate to a voltage oscillator (VCO) that uses a replica bias circuit to generate a cascode bias voltage. The VCO generate an output periodic signal having a frequency and phase that is less or not susceptible to voltage swings by using a bias voltage generated in a replica bias circuit that replicates a voltage-to-current converter in the VOC. The bias voltage is generated and regulated according to a power supply voltage that supplies power to the VCO to account for voltage variations in the power supply voltage.
