A new very simple cellular neural network universal machine structure is presented. By using a high gain unipolar sigmoid as the cell output nonlinearity the coefficient building blocks can be integrated with high density. The new design reaches cell density about 10 times larger than the previous ones. A 48/spl times/48 cell grid has been fabricated using a 0.5 /spl mu/m standard digital CMOS process. The cell structure is described and some system level measurement results are given.
