A Tunable Integrated Device for LFP Tracking
Résumé
Neural recording and processing systems are key- instruments for investigating brain mechanisms and exploring innovative solutions for neuroprosthetic devices. At early exper- imental stages, configurability is an important feature for the neural processing units. We present in this paper the design of a configurable ASIC, dedicated to the analysis of Local Field Potential spectral distribution in rats' deep brain region. We detail the filter bank design strategy, regarding specifications such as flexibility, low power consumption and high linearity range. Simulation results are presented with numerical and in vivo recorded neural signals.
