Claim 1

A fuzzy signal defuzzifier using charge coupled devices, comprising: a plurality of channels CH 1 to CH n for intaking and transferring a set of fuzzy data in parallel; a gate electrode G 1 being divided into two lengths b 1 and b 2 in each of the channels CH 1 to CH n ; buses B 1 and B 2 being connected to the gate electrode G 1 ; and means for sensing on each of the buses B 1 and B 2 the sum of charge existing behind the gate electrode G 1 in each of the channels CH 1 to CH n and multiplying by weighting factors as determined by division ratios b 1 and b 2 of the gate electrode G 1 in each of the channels CH 1 to CH n ; whereby the total charge of each of the buses B 1 and B 2 is described by the following formulae: VB.sub.1 =K{(b.sub.1·1 ×q.sub.1)+(b.sub.1·2 ×q.sub.2)+(b.sub.1·3 ×q.sub.3)+ . . . +(b.sub.1·n ×q.sub.n)} VB.sub.2 =K{(b.sub.2·1 ×q.sub.1)+(b.sub.2·2 ×q.sub.2)+(b.sub.2·3 ×q.sub.3)+ . . . +(b.sub.2·n ×q.sub.n)} wherein VB 1 =total outputs from the bus B 1 ; VB 2 =total outputs from the bus B 2 ; K=sensitivity coefficient determined by a circuit; b 1 ·i and b 2 ·i =effective areas of the gate electrode G 1 in each of the channels CH 1 to CH n , being divided into two lengths b 1 and b 2 ; and q 1 to q n (q i )=charges existing behind the gate electrode G 1 in each of the channels CH 1 to CH n ; and the total output as a representative value is obtained as the difference of the output signals at each bus B 1 and B 2 as described by the following formula: V=VB.sub.1 -VB.sub.2 =K[{(b.sub.1·1 ×q.sub.1)+(b.sub.1·2 ×q.sub.2)+ . . . (b.sub.1·n ×q.sub.n)}-{(b.sub.2·1 ×q.sub.1)+(b.sub.2·2 ×q.sub.2)+ . . . +(b.sub.2·n ×q.sub.n)}] wherein V=difference of the total output signals between VB 1 =total outputs from the bus B 1 ; VB 2 =total outputs from the bus B 2 ; K=sensitivity coefficient determined by a circuit; b 1 ·i and b 2 ·i =effective areas of the gate electrode G 1 in each of the channels CH 1 to CH n , being divided into two lengths b 1 and b 2 ; and q 1 to q n (q i )=charges existing behind the gate electrode G 1 in each of the channels CH 1 to CH n .
