Toward an analog VLSI implementation of adaptive resonance theory (ART2)

We describe the architecture for an analog VLSI implementation of the ART2 network. This design uses primary analog circuitry, with some digital clocking for controlling switches for storage and timing. The system operates in current-mode, which simplifies much of the circuitry. The network is broken into four major blocks and we describe the circuitry that can implement these blocks. This represents an important first step toward an analog hardware implementation of ART2.
