Active power-line interference attenuation in bioamplifiers
公开In this project, we have implemented a feedback circuit that reduces common mode electrical potentials on the human body, in order to improve the performance of bioelectric sensors. The technique, known as "driven right let" (DRL), uses a feedback-based interference cancellation method. The bioelectric sensors used were inexpensive, high impedance, electrode-amplifiers that were electrically isolated from the recorder. An interference attenuation of at least 10 times was observed. This report serves as a reference into DRL and bioamplifier circuits.
