A Novel Topology for Design and Development of Wireless Electro-oculogram Biopotential Amplifer

This paper illustrates a novel topology for the conditioning of electro-oculogram signals. The system is composed of a second order amplification chain and assures stability, speed and accuracy. The proposed configuration has been developed in order to make signal acquisition of biological signals such as electro-oculogram simpler and robust with low cost. The filters between the preamplification and the amplification stages eliminate the out-of-band frequencies before amplification. This reduces the possibility of interferences from high frequency noises and maximizes the dynamic power consumption. The presented topology holds clinical and rehabilitative control applications.
