Abstract

Recent advances [1]-[5] in capacitively-coupled chopper instrumentation amplifier (CCIA) demonstrated that long-term stabilized physiological signal recording strongly relies on the capability of the electrode-DC offset (EDO) cancellation. On the other hand, a short recovery time can alleviate the loss duration of the signal to be recorded when a sudden EDO change saturates the CCIA. This is crucial because the subject's motion or the electrode's reconnection to the subject can give rise to such sudden EDO change. Very often, employing a DC servo loop (DSL) can introduce a high-pass (HP) pole to the transfer function of the CCIA, suppressing the EDO nearby the DC frequency.
