Abstract:
Objective To design and implement the implantable part of cochlear implants, i.e. multi-channel implantable neural stimulator. Methods Based on programmable logic device (PLD), the design of hardware circuit utilized hardware description language through PDM decoding and ETC controlling precept. Results The multi-channel implantable neural stimulator could provide as more as eight outputs of the channel, and the resolution of the outputs were high. Conclusion The miniature stimulator which is portable and efficient, contains perfect error correcting system, and the stimulating waveforms produced by the stimulator accord with the charge balance, current limit and charge limit.
