Title (EN) VOLTAGE CONTROLLED OSCILLATOR WITH SIMULTANEOUS SWITCHING OF FREQUENCY BAND, OSCILLATION CORE AND VARACTOR SIZE
(FR) OSCILLATEUR COMMANDE EN TENSION AVEC UNE COMMUTATION SIMULTANEE DE BANDE DE FREQUENCE, NOYAU D'OSCILLATION ET FORME DE VARACTOR
Abstract:
(EN) The invention relates to a voltage controlled oscillator for generating a variable frequency. The oscillator comprises an oscillator core and a transconductive portion for compensating current losses in the oscillator core. The oscillator core comprises an inductive portion with at least one inductive element and a capacitive portion whose capacitance can be continuously varied by means of a control voltage for varying said frequency. The capacitive portion comprises multiple variable capacitive elements whose capacitance is continuously variable by means of said control voltage, each variable capacitive element being switchable for being added to or removed from the capacitive portion.
(FR) L'invention concerne un oscillateur commandé en tension permettant de générer une fréquence variable. Cet oscillateur comprend un noyau d'oscillateur et une partie transconductive permettant de compenser les pertes de courant dans le noyau d'oscillateur. Le noyau d'oscillateur comprend une partie inductive avec au moins un élément inductif et une partie capacitive dont la capacité peut être variée en continu au moyen d'une tension de commande permettant de varier cette fréquence. La partie capacitive comprend de multiples éléments variables dont la capacité est variable en continu au moyen de la tension de commande, chaque élément capacitif variable pouvant être commuté pour être ajouté à la partie capacitive ou retiré de cette partie capacitive.
