Abstract: This paper presents design methods for the designing and simulation of fuzzy membership functions (S, Z, trapezoidal and triangular) using operational amplifier in SPICE. This is the interactive tool which gets the design requirements for the system to be designed from the user. I have also calculated the electrical parameters like slew rate, common mode rejection ration, gain, power dissipation and resistances for each membership function. An operational amplifier is a DC coupled high gain electronic voltage amplifier with a differential input and a single ended output.

Keywords: operational amplifiers; fuzzy systems; fuzzy membership functions; SPICE; simulation; slew rate; common mode rejection; gain; power dissipation; resistance.
