Abstract
Cochlear implants restore partial hearing to people with severe to profound sensorineural deafness. Low-power wide-dynamic-range systems are hard to build. The biological cochlea is one of the most awesome examples of such system. It can sense sounds over 12 orders of magnitude in intensity with power dissipation of few tens of microwatts. Inthis paper, an analog band pass filter is implemented in AMS 0.35m CMOS technology. We used the Sallen-Key topology in the filter.
