Abstract :
This paper describes the stimulation management unit for a multichannel vestibular neural prosthesis. The unit is designed as part of a stimulator ASIC in the implantable subsystem of the prosthesis. This digital unit provides the stimulator ASIC the ability to generate biphasic current pulses at specified amplitude, duration and pulse rate to drive electrodes in the semicircular canals. The circuit was implemented in 0.6-μm CMOS technology and post-layout simulations are presented to show its operation.
