  • Abstract
    An ultra-low power spike detector has been developed for implantable neural recording microsystems. The proposed circuit amplifies neural spikes with a pre-amplifier with a gain of 25.5 dB and then signals are compared with a detection threshold in a 25 dB comparator circuit. The spike detector simulated in a 0.13 μm standard CMOS process consumes 56.5 μW while being biased from a 0.7 V power supply.
