Recording neural signal from a living human body is a complex task and it is an important research issues for neuroscientists and researchers in biomedical engineering. The major issue to over- come in the design of a system that is aimed at being implant into the human body is having a low power consumption, low noise circuit and small dimension to minimize tissue damage. In this paper, specific issues of the most important part of such a neural acquisition system are presented; in particular, the design of a low-power amplifier, for a fully implantable neural recording system, is described.

Abstract

In this paper, specific issues of the most important part of such a neural acquisition system are presented; in particular, the design of a low-power amplifier, for a fully implantable neural recording system, is described.
