A 128-Channel Level-Crossing-Based Neural Digitization and Spike Sorting SoC With Compact Spatiotemporal Feature Extraction.

High-density neural interfaces require power-efficient acquisition and on-chip processing for low-latency closed-loop operation. While level-crossing ADCs (LC-ADCs) offer efficient front-end acquisition, their integration with large-scale on-chip spike-sorting remains unexplored. In addition, existing on-chip spike sor...
