Abstract
The present disclosure relates to apparatuses and methods for treating neurological disorders by electro-stimulation. In some embodiments, the apparatus includes a stimulation module configured to generate a stimulation signal to be sent to at least one implantable electrode, and an acquisition module configured to acquire a signal measured by the at least one implantable electrode from a patient. The acquisition module may include a front-end block configured to amplify a potential difference of input signals (V1a, V2a) received by the acquisition module and to filter a stimulus artifact by cutting off frequencies above a predefined frequency band. The front-end block may include a multi-stage fully-differential switched capacitor circuit configured for discrete-time signal processing.
