Abstract :
A current-mode circuit based on square-root and squarer/divider circuits to realize the centre of gravity defuzzify strategy is described in this paper. The current-mode approach allows it to operate at 3.3 V without degrading its dynamic range. This proposed circuit had been fabricated in 0.8 μm single-polysilicon-double-metal technology, and the experimental results showed that it can operate with high speed and low power dissipation
