Cochlear Filters Design Using a Parallel Dilating-Biquad Switched-Capacitor Filter Bank

Lin, Jyhfong; Ki, Wing-Hung; Thompson, K.E.; Shamma, S. (1991)

A parallel filter bank is proposed to implement cochlear filters using very large time-constant (VLT) switched-capacitor (SC) filters. Significant hardware reduction is achieved in three ways. First, VLT SC biquads are ...

Realization of Cochlear Model by VLT Switched-Capacitor Filter Biquads

Lin, Jyhfong; Ki, Wing-Hung; Thompson, K.E.; Shamma, S. (1991)

We describe here the realization of a cochlear model using switched capacitor filters (SCF). This approach is made possible by a new design technique, called charge differencing (CD), which reduces by up to 50% the silicon ...
