Title
(EN) AN INDUCTOR LAYOUT, AND A VOLTAGE-CONTROLLED OSCILLATOR (VCO) SYSTEM
(FR) MONTAGE DE BOBINES D'INDUCTION ET SYSTÈME D'OSCILLATEUR COMMANDÉ EN TENSION (VCO)
Abstract
(EN)
An inductor layout (200, 300, 400) comprising a first inductor (210, 310, 410) and a second inductor (220, 320, 420). The first and second inductors (210, 310, 410; 220, 320, 420) are electrically and magnetically independent inductors concentrically arranged on an integrated circuit 800. At least one of the first and second inductors (210, 310, 410; 220, 320, 420) is a multi-loop inductor with a first axis (226a, 316a, 326a, 416a, 426a) of symmetry.
(FR)
Cette invention concerne un montage de bobines d'induction (200, 300, 400) comprenant une première bobine d'induction (210, 310, 410) et une seconde bobine d'induction (220, 320, 420). Les première et seconde bobines d'induction (210, 310, 410; 220, 320, 420) sont des bobines d'induction électriquement et magnétiquement indépendantes, agencées de manière concentrique sur un circuit intégré (800). Au moins une des première et seconde bobines d'induction (210, 310, 410; 220, 320, 420) est une bobine d'induction à boucles multiples présentant un premier axe de symétrie (226a, 316a, 326a, 416a, 426a).
