Abstract
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 (<1 uW), immunity from body effect and wide input dynamic range (>60 dB). Simulation results by Hspice confirm the validity of the proposed design technique and show high performance of the circuit.
