Title (EN) INITIAL PHASE CONTROL OF AN OSCILLATOR
(FR) CALAGE INITIAL D'UN OSCILLATEUR
Abstract: front page image
(EN)An initial phase control for an oscillator (100) such as a different ring voltage-controlled oscillator is disclosed. The initial phase control generally comprises a current source circuit coupled to a first node of the delay cell and a current provider. The current source circuit and current provider are preferably selectively and synchronously in an on or off state such that when the current source circuit and current provider are in an on state, the current source circuit draws a current through the first node of the delay cell and the current provider provides current through a second node of the delay cell. A method for controlling a delay cell and an initial phase control for a differential ring oscillator having a plurality of delay cells in a ring configuration are also disclosed.
(FR)Cette invention concerne une commande initiale de phase pour oscillateur (100) tel qu'un oscillateur différentiel en anneau commandé en tension. La commande de phase initiale comprend généralement un circuit de source de courant couplé à un premier noeud de la cellule de retard et un fournisseur de courant. Le circuit de source de courant et le fournisseur de courant sont de préférence sélectivement activés ou désactivés de manière synchrone de sorte que lorsque les deux sont activés, le circuit de source de courant prend un courant via le premier noeud de la cellule de retard et le fournisseur de courant assure l'alimentation par un second noeud de la cellule de retard. L'invention concerne également une technique de commande pour oscillateur différentiel à anneau comportant une pluralité de cellules de retard disposées en anneau.
