A CMOS implementation of current-mode min-max circuits and a sample fuzzy application

A new design of CMOS min-max circuits in current-mode is presented. These kinds of circuits have a growing number of fuzzy applications in fuzzy logic controllers. As a sample fuzzy application, membership function generator (MFG) based on min circuit, is presented. The proposed circuits have wide input and output dynamic range. A 3.3 V power supply has been applied and simulation results are presented in 0.35 /spl mu/m CMOS process.
