Abstract :
Current-mode analog circuits, i.e., a maximum (MAX) circuit, a minimum (MIN) circuit, and a defuzzified circuit, for fuzzy inference hardware systems, are proposed. The design of the proposed MAX and MIN circuits is based on simple bounded-difference equations. The defuzzifier circuit is synthesized using multipliers/dividers based on the translinear principle. The design considerations and the simulation results of a 2 × 2 fuzzy controller using the proposed circuits are described
