A highly accurate fully programmable fuzzifier in current mode approach

This paper presents a fully programmable compact analog CMOS realization of triangular/trapezoidal/z-shaped/s-shaped membership functions generator circuit in current mode approach. Analog realization of the programming units distinct the circuit from the previous works in power consumption, accuracy, speed, and continually parameters changing. Designed circuit was simulated by HSPICE simulator with level 49 parameters (BSIM3v3) and the simulation results verified the performance of the proposed fuzzifier. Finally, the presented layout of the fuzzifier shows it occupies less than 0.01mm2.
