In this paper, a new structure of voltage-mode MAX-MIN circuit is presented for fuzzy applications, neural network and etc. A differential pair with improved cascode current mirror is used to choose the desired input. The advantages of the proposed structure are high operating frequency, High precision, low power consumption, low area and simple expansion for multiple inputs by adding only three transistors for each extra input. The proposed circuit which is simulated by HSPICE in 0.35 mum CMOS process shows the total power consumption of 85 muw in 5 MHz operating frequency. Also, the total area of the proposed circuit is about 420 mum2 for two input voltages, and would be negligibly increased for each extra input.
