  • Abstract
    A 65nm CMOS 4.78mm2 integrated neuromodulation SoC consumes 417μW from a 1.2V supply while operating 64 acquisition channels with epoch compression at an average firing rate of 50Hz and engaging two stimulators with a pulse width of 250μs/phase, differential current of 150μA, and a pulse frequency of 100Hz. Compared to the state of the art, this represents the lowest area and power for the highest integration complexity achieved to date.
