Integrated low noise signal conditioning interface for neuroengineering applications

the birth of Neuroengineering, a new research field recently introduced by the synergic overlap between neuroscience and electronic engineering disciplines, injected a great enthusiasm in researchers. In fact, it opened a new perspective for addressing complex problems such as the understanding of the brain functions and the development of novel and advanced brain-computers. In this article, we offer a brief overview on implementations of integrated interface systems for neurobiological and electrophysiological in-vitro applications. After, we propose a system, still under development, aimed to achieving some hundreds of input channels. The architecture comprises a low-noise preamplifier stage and exhibits for each channel a power consumption of 90.05 μW and a silicon area of about 0.17 mm. Work is currently in progress to implement a fully integrated recording circuitry.
