A low-power analog logarithmic map circuit with offset and temperature compensation for use in bionic ears
… capturing the envelope of speech signals in a bionic ear. Fabricated in a 1.5 [mu]m process, the circuit consumes only 1 [mu]W of analog power and another 1 [mu]W of digital power, and can therefore run for over 50 years on just a couple of AA batteries. At the current level of power …

A low-power cochlear implant system
Cochlear implants, or bionic ears, restore hearing to the profoundly deaf by bypassing missing inner-ear hair cells in the cochlea and electrically stimulating the auditory nerve. For miniaturized cochlear implants, including behind-the-ear (BTE) models, power consumption is the chief factor in …
