Status: Published (early access).
This paper presents a 16-channel neural stimulator ASIC for prosthetic sensory feedback. An initialization phase presets the voltage across a series blocking capacitor to balance sourced and sunk charge, while speed-boosting feedback supports higher stimulation rates. The ASIC was fabricated in a 130-nm BCD CMOS process.
