The use of Field Programmable Analog Arrays (FPAAs) for analog conditioning of electric potentials on the surface of living tissue, such as Electrocardiography (ECG), is presented in this paper. The inherent reconfigurable capability of these devices provides versatility for circuitry dynamic tuning, i.e., changing amplification gains, filters corner frequencies, signal common levels, etc., without interrupting the signal acquisition path. A study of internal circuitry noise sources is presented and some configurations that attenuate noise effects are proposed.
