Abstract
We review how the nonideal properties of biopotential amplifiers can transform common mode voltage into interference. We then review several design approaches for two-and three-electrode amplifiers, both nonisolated and isolated, that reduce this interference. We consider the effects of static electricity on the various designs, and we show how to calculate the optimal values of the circuit components.Keywords
