Artifact-Free Neurostimulator with Arbitrary Waveform Generation for High-Channel, High-Density Bidirectional Neural Interfaces

To achieve greater specificity in neurostimulation, bidirectional neural interfaces are required to verify the recorded neural response after stimulation. The specific neural interface targeted in this thesis is the epiretinal implant. Due to the heterogeneity of the retinal ganglion cells (RGCs), high-fidelity vision is only possible when all...
