Title
(EN) CAPACITOR COMPENSATED DUAL OF POLYPHASE FILTER
(FR) FILTRE POLYPHASÉ À COMPENSATION DE CONDENSATEUR
Abstract
(EN)
A polyphase filter operates to provide capacitive compensation to drive a multiphase network for generating quadrature signals. The polyphase filter (220) can include a capacitive compensation mechanism (340,350) at internal nodes. The capacitive compensation mechanism includes a first phase lag circuit (340) between a first internal node (XI) and a second internal node (X2) and a second phase lag circuit (350) coupled between a third internal node (X3) and a fourth internal node (X4). The first internal node is coupled to the second internal node via a first inductor (320) coupled to a first resistor (Rp1), the second internal node is coupled to the third internal node via a second inductor (322) coupled to a second resistor (Rp2), the third internal node is coupled to the fourth internal node via a third inductor (324) coupled to a third resistor (Rp3), and the fourth internal node is coupled to the first internal node via a fourth inductor (326) coupled to a fourth resistor (Rp4).

Un filtre polyphasé fonctionne pour fournir une compensation capacitive pour attaquer un réseau polyphasé pour générer des signaux en quadrature. Le filtre polyphasé (220) peut comprendre un mécanisme de compensation capacitive (340, 350) au niveau de nœuds internes. Le mécanisme de compensation capacitive comprend un premier circuit de retard de phase (340) entre un premier nœud interne (XI) et un second nœud interne (X2) et un second circuit de retard de phase (350) couplé entre un troisième nœud interne (X3) et un quatrième nœud interne (X4). Le premier nœud interne est couplé au deuxième nœud interne par l'intermédiaire d'un premier inducteur (320) couplé à une première résistance (Rp1), le deuxième nœud interne est couplé au troisième nœud interne par l'intermédiaire d'un deuxième inducteur (322) couplé à une deuxième résistance (Rp2), le troisième nœud interne est couplé au quatrième nœud interne par l'intermédiaire d'un troisième inducteur (324) couplé à une troisième résistance (Rp3), et le quatrième nœud interne est couplé au premier nœud interne par l'intermédiaire d'un quatrième inducteur (326) couplé à une quatrième résistance (Rp4).
