Une analyse de la fréquence de résonance dans les lignes de transmission en court-circuit avec un condensateur inséré a été réalisée. L'analyse montre une dépendance de la fréquence de résonance en fonction de la position de la capacité sur une ligne de transmission en court-circuit. Deux méthodes d'analyse sont présentées pour prédire la fréquence de résonance et comprendre comment le condensateur inséré affecte la fréquence de résonance de la ligne de transmission en court-circuit. En utilisant ces connaissances, nous proposons une nouvelle structure pour les oscillateurs à commande numérique utilisant la dépendance de la sensibilité de la capacité en fonction de la position de la ligne de transmission en court-circuit afin d'augmenter la résolution en fréquence. Un oscillateur à commande numérique basé sur une ligne de transmission de 9 GHz a été conçu et fabriqué comme preuve de concept. Les résultats mesurés montrent qu'une augmentation de résolution de pas de fréquence plus de 100 fois supérieure est possible en utilisant la même taille de condensateur d'accord situé à différents points de la ligne de transmission.

Abstract: Analysis of resonance frequency in shorted transmission lines with inserted capacitor has been made. The analysis shows a resonance frequency dependence on capacitance position on a shorted transmission line. Two analysis methods are presented to predict the resonance frequency and understand how the inserted capacitor affects the resonance frequency of the shorted transmission line. Using this knowledge we propose a new structure for digital controlled oscillators utilizing the capacitance's sensitivity dependence on position of the shorted transmission line to increase the frequency resolution. A 9 GHz transmission line based digital controlled oscillator was designed and fabricated as a proof of concept. Measured results show that more than 100 times frequency step resolution increase is possible utilizing the same tuning capacitor size located at different points on the transmission line.
