This work reports on the design of an electronic interface performing biomedical signal measurements. The proposed system involves three functional blocks: two leading electrodes, the signal conditioning front-end and a feedback circuitry. In particular, the latter is able to balance the electrodes impedance mismatching so to reduce the noise contribution. In this paper, the design has been tailored for a heart signal recording, however this approach can be easily applied in other types of biopotential measurements requiring a reduced number of electrodes. The reported simulation results show that the proposed system can be a good candidate in some intensive biomedical signal recordings.
