Appraisal of a low noise electrocardiogram
Journal of the American College of Cardiology, 1983 Two low noise electrocardiographic systems were designed to record low amplitude His-Purkinje potentials in the PR segment and delayed depolarization potentials in the ST-T segment from the body surface on a beat to beat basis. In one system, a bipolar electrode was utilized and the noise level was optimally reduced to 2 to 2.5 microV by a combination ...

A Survey of Neural Front End Amplifiers and Their Requirements toward Practical Neural Interfaces
Journal of Low Power Electronics and Applications, 2014 When designing an analog front-end for neural interfacing, it is hard to evaluate the interplay of priority features that one must upkeep. Given the competing nature of design requirements for such systems a good understanding of these trade-offs is ...
