Abstract
The present disclosure includes methods, devices, and systems for cochlear implants. One method embodiment for cochlear implant signal processing includes processing a differential analog audio signal using amplitude modulation and pulse-width modulation. The method includes driving a transmission coil on an external unit of the cochlear implant with the pulse-width and amplitude modulated signal. The method also includes driving a reception coil on an internal unit of the cochlear implant with an output of the transmission coil.
