Abstract
An ultra wideband (UWB) 64-channel responsive
neural stimulator system-on-ch ip (SoC) is presented. It demon-
strates the first on-chip neural vector analyzer capable of wire-
lessly monitoring magnitude, phase and phase synchronization of
neural signals. In a closed-loop, abnormal phase synchrony trig-
gers the programmable-waveform biphasic current-mode neural
stimulator. To implement these functionalities, the SoC integrates
64 neural recording ampli fiers with tunable switched-capacitor
