“…Thus, in this case he chose a pulse-width-modulation scheme for the neural encoding as opposed to the pulse-frequencymodulation used in his 1993 effort. That same year the first current-mode cochleae designs arose; one from Christopher Abel (Abel et al, 1994) and one from Christofer Toumazou and Tor Sverre Lande (Toumazou et al 1994). The former effort presented a novel implementation of a silicon cochlea based on discrete-time, switch-current biquads.…”

A new design methodology is proposed to realize a real cochlea using the multiplexing switched-capacitor circuits. The proposed technique is based upon the transmission-line model proposed by Zwislocki (1950). At the cost of the increase in the number of clock phases, the decay rate in the transition region of the filter section can be increased by adding only a few components. Therefore, the components and chip area of the designed silicon cochlea can be small. An experimental chip containing four filter sections has been designed and fabricated. The measured frequency responses from the 32-section cochlea formed by cascading nine fabricated chips are consistent with both theoretical calculation results and observed behavior of a real cochlea. Moreover, the designed silicon cochlea has the dynamic range of 67 dB in each section and a low sensitivity to process variations. Thus it is suitable for VLSI implementation with the associated neural network.
