Abstract:
This article presents a 32-channel time-multiplexed highly digital neural recording front-end (RFE) that exhibits sub- $8.8~\mu $ s recovery latency from large stimulation artifacts while delivering high-resolution data at the Nyquist rate. The RFE is time-shared across 32 channels for low-frequency electrocorticography (ECoG) recording and across four channels for high-frequency action potentials (…
