Title (EN) METHODS AND APPARATUS TO GENERATE SMALL FREQUENCY CHANGES
(FR) PROCEDES ET DISPOSITIF PERMETTANT DE GENERER DES PETITES CONVERSIONS DE FREQUENCES
Abstract: front page image
(EN)In one embodiment, the present invention includes an apparatus having a first capacitor coupled between a first node and a second node, a second capacitor coupled between the second node and a reference potential, and a third capacitor coupled between the second node and a switch, where the switch is controllable to couple the third capacitor to the second node. Using such an apparatus small changes in capacitance and correspondingly small changes in frequency may be effected. Other embodiments are directed to calibration of one or more capacitor banks.
(FR)Un mode de réalisation concerne un dispositif comprenant un premier condensateur couplé entre un premier noeud et un second noeud, un second condensateur couplé entre le second noeud et un potentiel de référence, et un troisième condensateur couplé entre le second noeud et un commutateur, lequel commutateur peut être commandé de manière à coupler le troisième condensateur et le second noeud. L'utilisation d'un tel dispositif permet d'effectuer des petites conversions de la capacité et, ainsi, des petites conversions de fréquences. D'autres modes de réalisation décrits dans cette invention concernent l'étalonnage d'une ou de plusieurs batteries de condensateurs.
