Electrical stimulation of deep-brain or vagus nerve targets which are known to be effective in seizure abortion is started upon detection of a seizre onset. This paper focuses on the implantable part of the system including a high dynamic-range amplifier, a sub-ranging/amplification stage, a line-length feature extractor and a stimulator. The implantable part is integrated using a 0.18 mu m technology.Engineering, Electrical & ElectronicEngineeringclosed-loop electrical stimulationiot solutions for health-carehigh dynamic-range amplifierseizurestext::conference output::conference proceedings::conference paper
