  • Chronic recording of neural signals is indispensable in designing efficient brain machine interfaces and in elucidating human neurophysiology. [...] Key Method It can be biased adaptively from 200 nA to 2 uA, modulating input referred noise from 9.92 uV to 3.9 uV. We also describe a low noise design technique which minimizes the noise contribution of the load circuitry. The amplifier can pass signal from 5 Hz to 7 kHz while rejecting input DC offsets at electrode-electrolyte interface.Expand Abstract
