An Arbitrary Waveform 16 Channel Neural Stimulator with Adaptive Supply Regulator in 0.35 μm HV CMOS for Visual Prosthesis

We describe a neural stimulator front-endwith arbitrary stimulation waveform generator andadaptive supply regulator (ASR) for visual prosthesis. Each pixel circuit generates arbitrary currentwaveform with 5 bit programmable amplitude. TheASR provides the internal supply voltage regulated tothe minim...

Zusammenfassung:We describe a neural stimulator front-endwith arbitrary stimulation waveform generator andadaptive supply regulator (ASR) for visual prosthesis. Each pixel circuit generates arbitrary currentwaveform with 5 bit programmable amplitude. TheASR provides the internal supply voltage regulated tothe minimum required voltage for stimulation. Theprototype is implemented in 0.35 μm CMOS with HVoption and occupies 2.94 mm2 including I/Os. KCI Citation Count: 1
