Abstract: Current‐mode CMOS analog defuzzification circuits previously proposed are insensitive to absolute variation of the fabrication process and are easy to expand into a multiple‐input circuit. However, they have two disadvantages. One is that they need two input currents which are equal in magnitude and opposite in direction (sign). A current steering circuit which consists of current mirrors is used for changing the direction of the input current signals. However, because current mirrors are strongly influenced b…
