A Novel Programmable CMOS Fuzzifiers Using Voltage-to-Current Converter Circuit

Abstract EN

This paper presents a new voltage-input, current-output programmable membership function generator circuit (MFC) using CMOS technology.

It employs a voltage-to-current converter to provide the required current bias for the membership function circuit.

The proposed MFC has several advantageous features.

This MFC can be reconfigured to perform triangular, trapezoidal, S-shape, Z-Shape, and Gaussian membership forms.

This membership function can be programmed in terms of its width, slope, and its center locations in its universe of discourses.

The easily adjustable characteristics of the proposed circuit and its accuracy make it suitable for embedded system and industrial control applications.

The proposed MFC is designed using the spice software, and simulation results are obtained.
