A VLSI-ORIENTED CONTINUOUS-TIME CNN MODEL

This paper presents an analysis of the stability and convergence prope rties of the full signal range (FSR) CNN model, These properties are d emonstrated to be similar to those of the Chua-Yang model and the I/O mapping of known applications is shown to be unaffected by the modific ation introduced in this new model, In this modified CNN model the dyn amic range of the cell state variables equals the dynamic range of the cell output variables and is invariant with the application. This fea ture results in simpler circuit implementations, thus allowing higher cell densities and improving the robustness of CNN integrated circuits . The FSR CNN model is particularly well suited for programmable CNN i ntegrated circuits.
