Abstract
Nine basic fuzzy logic functions can be represented by the Bounded-Difference(s) and the Algebraic Sum(s). In current mode electronic circuits, the Algebraic Sum is implemented only by connecting wires (wired sum), and the Bounded Difference done by current difference and prevention of negative current. These fuzzy logic functions are implemented in the form of CMOS integrated circuits. The design criteria are also presented.
Tsutomu Miki passed away on December 1, 2012, when he was working at KIT as full professor.
