Title (EN) REPLICA CASCODE BIAS VOLTAGE-CONTROLLED OSCILLATORS
(FR) OSCILLATEURS COMMANDÉS EN TENSION À POLARISATION CASCODE DE RÉPLIQUE
Abstract: front page image
(EN)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.
(FR)Les modes de réalisation de l'invention se rapportent à un oscillateur commandé en tension (VCO) (100) qui utilise un circuit (103) de polarisation de réplique pour générer une tension de polarisation cascode. Le VCO (100) génère un signal de sortie périodique dont la fréquence et la phase sont moins sensibles ou pas sensibles aux excursions de tension, au moyen d'une tension de polarisation générée dans un circuit (103) de polarisation de réplique, lequel constitue une réplique d'un convertisseur tension-courant (101) dans le VCO (100). La tension de polarisation est générée et régulée selon une tension d'alimentation électrique qui alimente le VCO (100) en tenant compte des variations de tension de la tension d'alimentation.
