A novel reconfigurable membership function circuit (RMFC) for analog fuzzy logic controller (FLC) is presented. The reconfigurable characteristic makes it more suitable in industrial control applications when compared with the MFC proposed in [1]. By proper signal arrangement, the RMFC can re-sample the same input current in different configuration, which reduces the number ofMFC in analog FLC. Thus, the power consumption and circuitry are smaller than the MFC proposed in [2]. The full current mode circuitry ensures a low power supply voltage and high speed. The analog input signal is processed directly without any need of an A/D or D/A interface. SPECTRE simulation results validate the feasibility ofthe proposed RMFC that is implemented in 0.35 µm CMOS with a battery of 1.5-V supply. Key Words--Fuzzy logic controller (FLC),
