This demonstrator presents an ultra low power mixed-signal implementation of a cochlear prosthesis system. A laptop PC provides an audio stimulus to the cochlear chip. A microcontroller on the demonstrator board monitors the output channels of the chip and returns these to the PC to be displayed as a spectrogram. The audiological settings of the implant chip are controlled via a GUI running on the PC.
