A Compact Low-Power CMOS Analog FSR Model-Based CNN
Keywords:Cellular Neural Network, Four-Quadrant Multiplier, Analog Focal Plane Image Processing
A compact low-power CMOS analog circuit implementation of a Cellular Neural Network based on Full Signal Range Model (FSR-CNN) is presented. The required operations in cell definition are synapses (multiplication and summation) and saturated integration. In each synapse, a new multiplier architecture is employed with voltage and current inputs and a current output, which allows sharing building blocks and using continuously programmable weight values. Feasibility and usefulness of the proposed FSR cell architecture is verified through the simulation of two applications: the connected component detector and the border extractor.
