ABSTRACT:
A fuzzy computer includes a defuzzifier composed of charge coupled devices which intake and transfer a set of fuzzy data elements in parallel. Pairs of positive and negative gate electrodes are located transversely to the charge coupled devices. The gate electrodes in each pair differ in their effective area to the corresponding charge coupled devices and all the positive and negative electrodes are connected together in respective groups. Each of the positive and negative groups senses independently as an electronic signal, such as voltage, the sum of weighted charge value at each charge coupled device behind the electrodes, multiplying by the weighing factors which are determined by the effective area of each electrode. A total output is obtained as the difference of the output signals at the positive and negative electrode groups.
