Özet

In this paper, design and analysis of a novel current-mode defuzzification circuit is presented. The proposed defuzzification circuit is based on current-mode four-quadrant multipliers that have been constructed with simple current squarer and current differencing buffered amplifier (CDBA). This circuit has capable of high linearity, simple structure, and wide input current range. The defuzzification circuit has been simulated and verified by PSPICE with MIETEC 1.2 mu m parameters. The circuit is suitable for using Centre Of Gravity (COG) method in current-mode fuzzy logic controllers. The purpose of this paper is to present an alternative approach for current-mode defuzzification circuit design.
