Abstract :
This paper presents the design of a multichannel stimulator ASIC for an implantable neural prosthesis to restore 3-D vestibular sensation. The stimulator can provide the three semicircular canals with biphasic current pulses at rates between 1 and 500 pps with current amplitudes up to 1 mA. The ASIC was implemented in 0.6 μm HV CMOS technology and post-layout simulations are presented.
