Title
(EN) CURRENT GENERATION ARCHITECTURE FOR AN IMPLANTABLE STIMULATOR DEVICE INCLUDING DISTRIBUTOR CIRCUITRY FOR SENDING AN AMPLITUDE-SCALED CURRENT TO DIGITAL-TO-ANALOG CONVERTERS AT THE ELECTRODES
(FR) ARCHITECTURE DE GÉNÉRATION DE COURANT POUR UN DISPOSITIF DE STIMULATEUR IMPLANTABLE COMPRENANT DES CIRCUITS DE DISTRIBUTION POUR ENVOYER UN COURANT MIS À L'ÉCHELLE EN AMPLITUDE À DES CONVERTISSEURS NUMÉRIQUES-ANALOGIQUES AU NIVEAU DES ÉLECTRODES
Abstract
(EN)
An implantable pulse generator (IPG) is disclosed having an improved ability to steer anodic and cathodic currents between the IPG's electrodes. Each electrode node has at least one PDAC/NDAC pair to source/sink or sink/source a stimulation current to an associated electrode node. Each PDAC and NDAC receives a current with a magnitude indicative of a total anodic and cathodic current, and data indicative of a percentage of that total that each PDAC and NDAC will produce in the patient's tissue at any given time, which activates a number of branches in each PDAC or NDAC. Each PDAC and NDAC may also receive one or more resolution control signals specifying an increment by which the stimulation current may be adjusted at each electrode. The current received by each PDAC and NDAC is generated by a master DAC, and is preferably distributed to the PDACs and NDACs by distribution circuitry.
(FR)
La présente invention concerne un générateur d'impulsions implantable (GII) ayant une capacité améliorée à diriger des courants anodique et cathodique entre les électrodes du GII. Chaque nœud d'électrode inclut au moins une paire PDAC/NDAC pour envoyer/absorber ou absorber/envoyer un courant de stimulation à un nœud d'électrode associé. Chaque PDAC et NDAC reçoit un courant ayant une amplitude caractéristique d'un courant anodique et cathodique total, et des données indiquant un pourcentage de ce total que chaque PDAC et NDAC produira dans le tissu du patient à tout moment donné, ce qui active un certain nombre de branches dans chaque PDAC ou NDAC. Chaque PDAC et NDAC peut également recevoir un ou plusieurs signaux de commande de résolution spécifiant un incrément par lequel le courant de stimulation peut être ajusté au niveau de chaque électrode. Le courant reçu par chaque PDAC et NDAC est généré par un DAC maître, et est de préférence distribué aux PDAC et NDAC par des circuits de distribution.
