We report on a vestibular prosthesis signal processor realized using an experimental field programmable analog array (FPAA). Completing signal processing functions in the analog domain, the processor is designed to help replace a malfunctioning inner ear sensory organ, a semicircular canal. Relying on angular head motion detected by an inertial sensor, the(More)
A custom analog vector matrix multiplier (VMM) for a vestibular prosthesis is reported. The VMM functions to reduce misalignment between implanted angular rate sensors and associated peripheral sense organs and precompensate for spurious electrical stimulation of vestibular neurons. Operating in the CMOS subthreshold region, the VMM performs a 3-by-3 vector(More)
