Abstract

A novel high speed and tunable transconductor suitable for analog and mixed-signal fuzzy circuits operating in current mode and a high linear MIN circuit are proposed. Using this OTA, we construct are high speed Gaussian and trapezoidal-shaped fuzzifier and implement S-shaped and Z-shaped function with all parameters (slop, width, and position) independently and continuously tunable, and excellent for low voltage application. Computer simulations verify the performance of this circuit, showing high speed (up to 100MHz) and a high support range. The purposed circuits were developed in CMOS 0.18μm technologies.
