Abstract

This project aims to study some CMOS topologies of integrated amplifiers for biopotential signals that are capable of canceling the continuous part of the input signals without external capacitors. Such continuous part of the signals is frequent in sources like electrocardiograms, but has no significant information for the exam results. We intend to use circuit and device simulation, and to implement some circuits trhoug multiuser rograms, in order to obtain experimental results.
