In this paper, we present the design of an epilepticseizure detector. This circuit is part of an implantable device used to continuously record intracerebral electroencephalographic signals through subdural and depth electrodes. The implemented seizure detector is based on a detection algorithm validated in Matlab tools and the circuits were implemented using CMOS 0.18-μm process. The proposed system...
In this paper, we present a seizure detector that is part of an implantable CMOS integrated device intended to identify seizure onsets and trigger focal treatment to disrupt seizure progression. The detector consists of a preamplifier, voltage level detectors, digital demodulators and a high-frequency detector. Variable gain amplification, adjustable threshold voltage identification and tunable recognition...
