Abstract
Disclosed herein are apparatuses and methods for treating neurological disorders by electro-stimulation. The apparatus for treating neurological disorders includes at least one electrode implantable in the brain of a patient, and a processing and stimulation device connected to the at least one electrode. The processing and stimulation device may include a stimulation module configured to generate a stimulation signal to be sent to the at least one electrode, and an acquisition module that measures cerebral activity coming from the brain of the patient. The acquisition module may have a front-end block configured to amplify the potential difference of its input signals (V1a, V2a) and to filter a stimulus artifact and may include a multi-stage fully-differential switched capacitor circuit (e.g., an integrated circuit) configured for discrete-time signal processing.
