Circuits for an RF cochlea

Abstract

We develop a technique for approximating a WKB-type solution to a wave equation as a cascade of unidirectional filters. This allows us to design improved building-block circuits for a bio-inspired RF cochlea. By comparing properties of different cochlear filter stages using experimental results and circuit simulations, we demonstrate that our technique… (More)
