AER EAR: a matched silicon cochlea pair with address event representation interface

In this paper we present an analog integrated circuit containing a matched pair of silicon cochleae and an address event interface. Each section of the cochlea, modeled by a second-order low-pass filter, is followed by a simplified Inner Hair Cell circuit and a Spiking Neuron circuit. When the neuron spikes, an Address Event is generated on the asynchronous data bus. Measurements with pure tones played from different positions are presented.
