Abstract :
A new cochlear implant microstimulator is described. It consists of a full custom integrated circuit designed in 3 μm CMOS technology. The main feature of the targeted device is its “transparency” to the stimulation algorithms, that is, no internal constraints have been imposed to make its design dependent of any stimulation pattern. The resulting chip has a microprocessor architecture executing 32-bit command words to generate different output current waveforms through sixteen outputs
