Abstract: Recorded neural knowledge are often corrupted by massive amplitude artifacts that are triggered by a range of sources, like subject movements, organ motions, electromagnetic interference's and discharges at the electrode surface. to forestall the system from saturating and therefore the electronics from non functioning because of these massive artifacts, a large dynamic vary for information acquisition is demanded, that is kind of difficult to attain and would need excessive circuit area and power for implementation. in this paper, we tend to present a high-performance Delta-Sigma modulator beside many design techniques and enabling blocks to cut back circuit area and power. These competitive circuit specifications create this design a decent candidate for building high preciseness neurosensory.

Keywords: Sensor interface; dynamic range; multi-bit quantizer; switched op-amp; Delta-Sigma modulator.
