A new structure of current mode min-max circuit using CMOS technology for fuzzy applications

In this paper a new structure of current mode minmax circuit is presented. The proposed structure can detect minimum and maximum of the input current signals simultaneously. It has advantages of analog design such as 1.5 percent error in maximum amplitude and low power consumption. Hence, the proposed circuit has high precision. The proffered circuit involves 14+4 transistors using 0.18um CMOS standard technology. A 1.8 (V) power supply is applied and the Monte Carlo, corner, pulse and other simulations for checking performances of the proposed circuit have been done using HSPICE level49 (BSIM3v3) software. Also, the layout pattern of the proposed circuit is drawn by CADENCE software.
