摘 要：This dissertation presents two complete neural interface systems to address two key challenges:evading the brain's foreign body response to achieve long probe longevity,and scaling wireless, implantable systems to high channel counts.The first,a self-contained, 0.125 mm2, 4-channel wireless recording system, achieves an  unprecedented level of miniaturization.The second system achieves an unprecedented level of integration, combining 64 recording channels, 16 stimulation channels, and neural data compression onto a single 4.78 mm2 IC. Furthermore, the IC achieves substantial improvements in power and area versus state-of-the-art.
