A low-power current-mode defuzzifier for fuzzy logic controllers
Ebrahim Farshidi · 2008
In this paper a new current-mode circuit to realize the center-of gravity (COG) defuzzifier is presented. The circuit employs floating-gate MOS (FG-MOS) transistors that operate in weak inversion region. Compared to the other proposed circuit, this circuit features severe reduction of the elements number, low supply voltage (0.7 V), low power consumption (60 dB). Simulation results by Hspice confirm the validity of the proposed design technique and show high performance of the circuit.
