Abstract:
This article presents a direct-digitization interface for ExG bio-signals’ readout that simultaneously achieves a high dynamic range (DR) and a low noise-efficiency factor (NEF). The proposed delta amplification (DA) and feedback cancellation technique reduce both the input and output ranges of the first amplifier, thus allowing the use of a …
