Title:
REPLICA CASCODE BIAS VOLTAGE-CONTROLLED OSCILLATORS
Document Type and Number:
WIPO Patent Application WO/2016/179789
Kind Code:
A1
Abstract:
Embodiments relate to a voltage oscillator (VCO) (100) that uses a replica bias circuit (103) to generate a cascode bias voltage. The VCO (100) generates 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 (103) that replicates a voltage-to-current converter (101) in the VCO (100). The bias voltage is generated and regulated according to a power supply voltage that supplies power to the VCO (100) to account for voltage variations in the power supply voltage.
