A High Speed and Compact Mixed-Signal CMOS fuzzifier

A novel high speed linear tunable transconductor suitable for analog and mixed-signal fuzzy circuits operating in current mode is proposed. Using this OTA, we construct a high speed fuzzifier, and implement trapezoidal /triangular functions with all parameters (slope, width and position) independently and continuously tunable, and excellent for low voltage applications. Computer simulations verify the performance of this circuit, showing high speed (up to 100MHz) and a high support range (up to 2.5V).
