ABSTRACT
In this paper, a novel VLSI architecture adaptation of the Cellular Neural Network (CNN) paradigm is described. It is based on a combination of MOS transistors operating in weak inversion regime. This combination has enabled a CMOS implementation of a simplified version of the original CNN model with the main characteristics of low-power consumption. Digitally selectable template coefficients are employed and a local logic and memory are added into each cell providing a simple dual computing structure (analog and digital). A four-quadrant analog multiplier is used as a voltage controlled current source which is feeding from the weighting factors of the template elements. The main feature of the multiplier is the high value of the weight voltage range which varies between the ground voltage and the supply voltage. A simulation example for stability of a class of nonreciprocal cellular neural network with opposite-sign template is presented.
