Hardware neuron models with CMOS for auditory neural networks

A number of studies have recently been made on hardware implementation of a neuron model for applications to information processing functions of neural networks. We previously proposed the transfer function which changes the threshold of a pulse-type hardware neuron model (hereafter, "P-HNM") in time according to an output that express feature-detecting cell and a universal-type hardware neuron model using depletion mode MOSFETs (hereafter "D-MOSFETs"), resistors, and capacitors. However, because it is difficult to make D-MOSFETs due to a complicated manufacturing process, they are not usually used in IC implementation. In this paper, we propose hardware neuron models with CMOS for feature-detecting cells of auditory neural network.
