Multiple-input OTA based circuit for cellular neural network-implementation in VLSI CMOS technology

An operational transconductance amplifier with multiple inputs, each of them realized by means of two MOSFETs only, suitable for implementation of cellular neural networks in CMOS technology is described. Preliminary analysis of a short-channel circuit augmented by SPICE simulation is given. Results show the potential for designing chip area effective networks applicable to various tasks of image processing and pattern recognition in real time. Additional research, in particular in the area of VLSI implementation, is needed.<
