L'oscillateur à commande numérique (DCO) basé sur LC est l'un des composants les plus importants de toutes les boucles numériques à verrouillage de phase. Les performances des boucles sont largement déterminées par la résolution fréquentielle du DCO. Afin d'améliorer la résolution en fréquence, nous proposons un réseau de capacités commutées à commande numérique basé sur des paires de condensateurs non adaptées, ce qui réduit considérablement la capacité minimale du varactor commuté. De plus, nous implémentons un DCO basé sur notre proposition en SMIC 0.18 µm et effectuons une simulation dans Spectre. Les résultats de la simulation montrent que la résolution en fréquence est améliorée par rapport aux méthodes existantes.

Abstract: The LC-based Digitally Controlled Oscillator (DCO) is one of the most important components of all digital phase locked loops. The performance of the loops is significantly determined by the DCO's frequency resolution. In order to enhance the frequency resolution, we propose a mismatched capacitor pairs based digitally controlled switched capacitance array, which dramatically reduces the minimum switched varactor capacitance. Furthermore, we implement a DCO based on our proposal in SMIC 0.18 µm and conduct simulation in Spectre. The simulation results show that the frequency resolution is enhanced compared with the existing methods.
