Abstract
A CMOS integrated circuit implementation of a programmable membership function generator (MFG) for a fuzzy logic controller (FLC)is presented in this paper. This MFG accepts differential input voltages and generates differential output currents and implements gausian functions with all parameters (slope, position, width and height) independently and continuously adjustable. Higher Power Supply Rejection Ratio is also achieved by the lise of differential structure. Designed circuits to implement these types of membership functions are simulated using HSPICE by level 49 parameters (BSIM3v3) in 0.35μm standard CMOS technology. Power consumption of circuit is about 100µW and the chip occupies an area of 400 µm2 .
