Title (EN) STIMULATION WAVEFORM GENERATOR FOR AN IMPLANTABLE MEDICAL DEVICE
(FR) GÉNÉRATEUR DE FORME D'ONDE DE STIMULATION POUR UN DISPOSITIF MÉDICAL IMPLANTABLE
Abstract: front page image
(EN) This disclosure describes techniques for generating stimulation current pulses that have differing pulse shapes in a medical device. A circuit architecture is described that is configured to charge a capacitor to an initial amount of charge, modulate the amount of charge stored in the capacitor based on a control signal, and generate a stimulation current pulse that has an amplitude based on the amount charge stored in the capacitor. The circuit architecture may be configured to generate complex pulse shapes, such as, e.g., steps, ramps, bursts, and combinations thereof.
(FR) La présente invention concerne des techniques pour générer des impulsions de courant de stimulation qui ont des formes d'impulsion différentes dans un dispositif médical. Une architecture de circuit est configurée pour charger un condensateur à une quantité de charge initiale, moduler la quantité de charge stockée dans le condensateur sur la base d'un signal de commande et générer une impulsion de courant de stimulation qui a une amplitude basée sur la quantité de charge stockée dans le condensateur. L'architecture de circuit peut être configurée pour générer des formes d'impulsion complexes, telles que, par exemple, des pas, des rampes, des salves et des combinaisons de ceux-ci.
