文摘

A DRL compensation is presented allowing higher common mode voltage attenuation. Dry electrode and single-ended systems can benefit from the proposed high gain DRL. The stability margin and simplicity of the established alternative are preserved. A design procedure and sample implementation for a dry electrode system are shown. Better rejection of power line harmonics is experimentally demonstrated.
