A low-power analog VLSI system that implements a model of sound localization in the horizontal plane is designed, fabricated, and tested. The model uses the time difference between a sound arriving at each ear to determine the location of the sound source. The system consists of two chips in a standard 2 μm, p-well CMOS process. One chip contains circuitry to model left and right side cochleas, hair cells, and auditory neurons, while the other chip contains circuitry to model the binaural cross-correlation activity of neurons in the superior olive of the brain stem. Measured test results reveal challenges that must be overcome in order to obtain reliable products
