摘要
One of the active areas of fuzzy logic applications is control systems. In this paper presents a proposed Fuzzy Logic Controller (FLC) chips utilized a novel Membership Function Circuit (MFC) which can be made programmable. This membership function is simply tunable by setting some voltages on IC pins. Each input of controller has five membership functions and output has seven singletons. A new structure for Min/Max operators is presented, and also, a new current-Mode divider circuit with very small area and very low power consumption are presented, which are compatible to the proposed MFC, are also given. This controller is a general-purpose two-input one-output fuzzy controller that can be implemented in 0.08mm(2) in 0.35 mu m CMOS technology. The maximum delay in output of FLC is about 67 ns that correspond to 15 MFLIPS (Fuzzy Logic Inference per Second) and power consumption is 2.5mw.
