在本文中，我们介绍了一种模拟集成电路，它包含一对匹配的硅耳蜗以及一个地址事件接口。耳蜗的每一部分都由一个二阶低通滤波器建模，后面接着一个简化的内毛细胞电路和一个脉冲神经元电路。当神经元产生脉冲时，在异步数据总线上会产生一个地址事件。我们展示了芯片特性测试的结果以及使用地址事件表示（AER）EAR进行的基于双耳时间差的声音定位实验的结果。该芯片采用3层金属、2层多晶硅、0.5微米CMOS工艺制造。
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. We present the results of the chip characterization and the results of an interaural time difference based sound localization experiment using the address event representation (AER) EAR. The chip was fabricated in a 3-metal 2-poly 0.5-mu m CMOS process.
