Abstract
A novel circuit is presented for implementing a bidirectional passive cochlear model in analog VLSI. The circuit includes a subcircuit for modelling the fluid in the cochlear duct, and a subcircuit for modelling the passive basilar membrane. The circuit is compared to the classical 1-D transmission line cochlear model and found to be equivalent. The approach leads to an unexpected fa.ult tolerance in the form of insensitivity to transconductance amplifier offset voltages. A 545-stage cochlea has been fabricated and demonstrates the expected wave propagation behaviour.
