Abstract: According to an embodiment, a max-pooling neuron with first and second integrator circuits, a comparator circuit, a Schmitt trigger circuit, and a pair of switches is provided. The first and second integrator circuits, respectively filter a first and a second input train from a first and a second neuron of a previous layer to generate a corresponding first and second filtered input train. The comparator circuit amplifies a difference between the first and second filtered input trains and generates an amplified differential signal. The Schmitt trigger circuit generates a binary output signal based on the amplified differential signal. The pair of switches have a common first terminal coupled to an output node of the max-pooling neuron and a common control terminal coupled to the output terminal of the Schmitt trigger circuit. The other terminals of the pair of switches are coupled to respective input trains.
