Measured Bode magnitude plot (a) and input-referred noise (b) of the proposed instrument’s biopotential recording AFE. (a) The biopotential recording AFE provides a passband between 0.5 and 500 Hz. The roll-off of the analog high- and low-pass filters equals + 10 dB/Oct and − 40 dB/decade, respectively. (b) Noise power spectral density estimate in the passband for the biopotential recording AFE is 8 nV/√퐻푧Hz, with the residual 1/f corner estimated at roughly 5 Hz
