“…In the case of the spike sorting approach simulated here, the simplicity of the on-chip calculations indicates that the decrease in power consumption due to data reduction overcomes the power needs to perform those calculations. Based on the power requirements reported in low-power neural interfaces(Lopez et al, 2012, Gibson et al, 2013, Karkare et al, 2013, Wattanapanitch and Sarpeshkar., 2011, Rush and Troyk., 2012), we can estimate the power consumption of this hypothetical chip and assess its feasibility. Assuming an analog front-end (AFE) performing amplification, filtering, and ADC at 7 kHz and 10-bit resolution we estimate a spending of approximately 10 μW per channel only for this step (Wattanapanitch and Sarpeshkar., 2011).…”
